BUSCH FAMILY, NO. 18 TEAM VISIT THE WHITE HOUSE

As part of his Sprint Cup championship duties, Kyle Busch had one more thing left on his to-do list: visit the White House. So that's exactly what he did on Wednesday with the entire No. 18 Joe Gibbs Racing team and wife, Samantha.

And no, Brexton wasn't in attendance, but President Obama gave him a nice, little shout-out.

Follow along on the crew's trip to Washington, D.C.

LAST TIME

In September of 2015, Kevin Harvick punched his ticket to advance to the next round of the Chase for the NASCAR Sprint Cup by leading 355 of 400 laps at Dover International Speedway, a career-best at any track. Harvick beat out eventual 2015 Sprint Cup Series champion Kyle Busch by 2.639 seconds for the victory. 

YOU SHOULD KNOW


• Chris Buescher (-30 from 12th place), Tony Stewart (-11), Austin Dillon (-5) and Jamie McMurray (-5) are all on the outside looking in as far as the Chase Grid standings are concerned. Of those drivers, Stewart is the only one who has won at the "Monster Mile" -- three times to be exact. Stewart's most recent win came in 2013.

• With 10 wins, six-time Sprint Cup Series champion Jimmie Johnson has been to Dover's Victory Lane more times than any NASCAR driver. Johnson is looking to punch his ticket to the next Chase for the NASCAR Sprint Cup round and a win at his best track could be in the cards.

• Winning the opening XFINITY Series Chase race at Kentucky, Elliott Sadler continues his momentum to Dover where he has earned three top five and 10 top-10 finishes, two of which came in the last two XFINITY Series races at the 1-mile track. Sadler's experience in 17 starts at Dover could shine through on Saturday compared to the young guns he's competing against for the championship.

• Of the Camping World Truck Series Chase drivers, only Johnny Sauter and Timothy Peters have wins at Las Vegas Motor Speedway. Canadian Tire Motorsport Park winner John Hunter Nemechek has the best average finish of 4.0 out of the Truck Series Chase drivers. Behind Nemechek is Ben Kennedy with 5.0. Nemechek has run just one Truck Series race at Dover, while Kennedy has experienced two. In 15 starts, two-time Camping World Truck Series champion Matt Crafton has an average finish of 11.9, but is still seeking a win.

THE FAVORITE

Jimmie Johnson. Who better to pick than the 10-time Dover winner as this weekend's victor? With a championship at stake, Johnson is comfortable under pressure and is looking like a solid pick to win on Sunday.

Others to consider: Kevin Harvick, Martin Truex Jr.

THE SLEEPER

Kyle Larson. In five starts, the No. 42 driver has come as close as second (2016 spring race) to a win at Dover and has earned a total of four top-10 finishes. Larson earned his first Sprint Cup Series win this season and that victory could have given the boost to break the runner-up ceiling at the "Monster Mile." 

Others to consider: Tony Stewart, Chase Elliott.

STEWART NOT INTERESTED IN PLAYING NUMBERS GAME

CHARLOTTE, N.C. -- Crunch the numbers. Do the math. But don't bother telling Tony Stewart the potential scenarios required for him to advance to the Round of 12 in this year's Chase for the NASCAR Sprint Cup.

You'd be wasting your time and his time, too.

The only scenario Stewart, 45 and three times a Sprint Cup Series champion, cares about is the one that ends with him and his No. 14 Stewart-Haas Racing team celebrating in Victory Lane this weekend at Dover International Speedway.

"All we can do is go out and do the best we can this weekend," Stewart said Wednesday during a daylong media stop in downtown Charlotte, North Carolina. "It still amazes me how people can take something that's so simple and make it so complicated. 'Will we be watching where everybody else is?'

"Well yeah, I can waste my time and do that but … I've got to focus on winning the race. Because if I win the race I don't have to worry about where they're at. But if I go and do everything I can to try and win the race and I finish second, then wherever they are is wherever they are. I can't control those guys on the race track so why focus your attention on it? It's a waste of time."

The 2016 NASCAR Sprint Cup Series season is the final one for Stewart. He'll remain involved in the series as co-owner of Stewart-Haas Racing, which fields four Sprint Cup teams and one that will debut a NASCAR XFINITY Series entry next year. He's a track owner, team owner and competitor in other series -- some NASCAR-affiliated, some not -- as well.

But his quest for a fourth title rests solely on the outcome of Sunday's Citizen Soldier 400 at Dover (2 p.m. ET, NBCSN, MRN, SiriusXM NASCAR Radio). A 16-driver field that began the Chase two weeks ago will be trimmed to 12 after Dover, and Stewart will arrive Friday 15th on the Chase Grid.

His approach to what could be his final race as a title contender will be no different than any other weekend.

"There is no mindset to it," he said. "The most realistic mindset to go into it with is the same approach you go into it with every weekend of the year and that's to go try to win the race. If you don't, get the best finish you can get out of it. That's not glamorous and that's not what you want to hear … but it's literally that simple. Go try to win the race. Do everything you can to win the race. If you can't win the race, try to finish second. If you can't finish second, try to finish third. It is as simple as it can possibly get."

That Stewart is in this predicament is something of a surprise, given the strong summer run that saw him collect six top-10 finishes, including a win at Sonoma, in eight races. The No. 14 team, headed up by crew chief Mike Bugarewicz, seemed primed for a possible run at yet another title.

But the results of the most recent six races weren't nearly as impressive, with no finish higher than 16th.

"These things are such science projects," Stewart said of today's cars, "and pretty much the whole (SHR) organization fights the same thing. It's whichever one can find the solution first."

Teammate Kevin Harvick has guaranteed himself a spot in the Round of 12 with a win this past weekend at New Hampshire and Kurt Busch can advance either by points, depending on his finish, or with a victory. Teammate Danica Patrick is the only SHR entry not in the Chase field.

"We're going to have to rely on Kevin and Rodney (Childers, crew chief), Kurt and (Tony) Gibson (crew chief) for sure and do the best we can," Stewart said. "We weren't totally terrible at the spring race but definitely have to be better than we were to get done what we need to get done."

Scenarios? Talk to Stewart at Homestead, if he happens to be one of the championship four. That's when he'll be more aware of such things.

"When you get to the last race of the year and you're racing for a championship and you've got enough of a lead that no matter what, if you finish from here on up, then yeah, you think about that," he said.

"But that’s not the scenario we're in."

DALE JR. POSTS UNEDITED* VIDEO OF HIS "TALKING" DOGS

Dale Earnhardt Jr.'s "talking" dogs, Gus and Junebug, enjoy a level of celebrity that few other dogs have ever reached. Unfortunately, it doesn't really look like the two get along as well as he would probably like. Perhaps because the "dog days" of summer are over?

Junior posted this video on Instagram Wednesday of his dogs. We promise this video has in no way been altered from the original.

The 2015 XFINITY Daytona winner has been racing in the XFINITY Series for three full seasons and has yet to attempt a Sprint Cup start in his racing career. He is currently one of the eight XFINITY drivers vying for the series championship in the inaugural Chase.

CHASE BUBBLE WATCH: ANALYZING THE PLAYOFF PICTURE AHEAD OF DOVER

Two races into the Chase for the NASCAR Sprint Cup and several drivers are in jeopardy of not advancing past the Round of 16, which ends next Sunday at Dover International Speedway (2 p.m. ET, NBCSN, MRN, SiriusXM NASCAR Radio). Let's find out which drivers are resting comfortably following Sunday's Bad Boy Off Road 300 at New Hampshire Motor Speedway.

Who's hot: Kevin Harvick. Harvick came into Loudon one point shy of advancement after a dismal showing (20th) in the Chase opener in Chicago. The 2014 champion and the man nicknamed "The Closer" came on strong on the final restart to take the lead on Lap 295 and nab a win and a locked-in spot in the Round of 12. The victory, in which he only led eight laps, has to erase a little bit of the bitter taste from last fall's race at New Hampshire, where Harvick led 216 laps but ran out of fuel with two to go.

Matt Kenseth. Kenseth came into this race with two straight wins at the "Magic Mile" and looked to be closing in on his third-straight win before Harvick surged on a late restart. The 2003 champion led 105 laps en route to a runner-up finish and moved up to fourth in the standings, 25 points to the good of transferring into the next round.

Kyle Larson. A top-10 finish at Loudon moved Larson from 15th in the standings (two points back of the last transfer spot) to 12th and five points to the good. It was an up-and-down weekend for the third-year driver, who didn't show the same speed in the race he had shown in practice. Still, he is on the right side of the bubble heading to Dover, where the Chip Ganassi Racing with Felix Sabates driver has an average finish of 6.2 and led 85 laps in the spring en route to a runner-up finish.

Who's not: Tony Stewart: The three-time champion was stuck a lap down for much of the second half of the race and finished 23rd, the second-lowest finish among the Chase field. The result had to be disappointing for "Smoke" after a runner-up showing at New Hampshire in July. Following a summer surge thanks to his Sonoma win, Stewart has not notched a top-10 finish in six races and is on the wrong side of the Chase cut line heading to Dover.

Austin Dillon. The weekend started rough when a wreck in the latter stages of the opening practice forced the Richard Childress Racing No. 3 team to pull out a backup car. Dillon's 16th-place finish was aided by a few late cautions to get him back on the lead lap, but he is still five points behind the cutoff line. On top of that, his overall numbers at Dover (see below) have the Chase rookie in a very tough spot to advance.

Four in, four out: Here's a look at the Chase bubble, with four drivers being eliminated after the third race of this round, at Dover International Speedway.

After win eludes Kyle Busch at Loudon, he's taking nothing for granted

After the second race in the opening round of the Chase for the Sprint Cup, Kyle Busch is third in the points standings and in position to advance to the Round of 12 to continue his title defense.

Kyle Busch seemed like he was right where he wanted to be as the laps wound down in last Sunday's Bad Boy Off Road 300 at New Hampshire Motor Speedway.

He had worked his way up to third and was on fresher tires than the two cars in front of him --€“ Kevin Harvick and Matt Kenseth. He was turning the faster laps and appeared to be running them down.

Then a couple things happened to prevent Busch from winning the race.
He ran out of time and the harder and longer he ran on his tires, the less fresh they became and the more his lap times started equaling out to the times being posted by the leaders. Busch ended up finishing third behind Harvick and Kenseth, who came home 1-2.

Busch also lamented the lack of lapped traffic the top three cars encountered over the closing laps. That could have slowed down the leaders and enabled him to catch them for a late run at the lead.

"It's always tough here to pass and it's always tough with the more laps you get on your tires compared to everybody else," Busch said after the race at New Hampshire. "They start to equal out and then you get into that aero disadvantage a little bit and probably with not ever getting into traffic, there was never going to be a chance for us to kind of mix it up with lapped cars."

Busch admitted that his No. 18 Joe Gibbs Toyota was not quite as fast as the other two cars with all things being equal. He just hoped his fresher tires and some lapped traffic would provide enough of a difference to tilt the circumstances in his favor at the end.

It just didn't quite play out that way.

"It was just going to be car-on-car, driver-on-driver and we just didn't get to see it," Busch said. "I felt like we could have stacked up against them having the tire advantage. We wouldn't have won if it was just heads up."

They didn't win, of course, but the third-place finish gives Busch a comfortable 33-point cushion heading into the final first-round Chase race. After this Sunday's race at Dover International Speedway, the current 16-driver Chase field will be trimmed to 12.

Despite the seemingly insurmountable advantage, the defending Sprint Cup champion insisted he isn't taking advancement into the next round of the Chase playoffs for granted.

"We've seen anything happen in this business, so I don't like it very much at all -- but it's certainly better than having a one-point cushion," Busch said. "There are pluses and minuses in this business, but anything can happen.

"We saw it with the 48 (car of Jimmie Johnson) last year --€“ they had issues at Dover. We've had issues before and we've been able to make our way through or we've been knocked out like in years prior. You just have to go and fight it out and try to keep track of that big picture and do what you need to do to move on."
