WHO’S OUT

PennsylvaniaGov. Josh Shapiro: Endorsing Harris

Shortly before Biden’s bombshell announcement, Shapiro gave an interview where he was asked directly whether he would run as vice president on a ticket headed up by Harris.

"I'm not going to get into hypotheticals,” said Shapiro. “The president has made clear he is running, [and] I am proud to serve as Pennsylvania governor.”

But it was only a few hours after Biden’s withdrawal before Shapiro joined in endorsing the vice president.

I’ve known Kamala Harris for nearly two decades—we’ve both been prosecutors, we’ve both stood up for the rule of law, we’ve both fought for the people and delivered results. Kamala Harris is a patriot worthy of our support, and she will continue the work of generations of Americans who came before us to perfect our union, protect our democracy, and advance real freedom. She has served the country honorably as Vice President and she is ready to be President.The best path forward for the Democratic Party is to quickly unite behind Vice President Harris and refocus on winning the presidency. … I will do everything I can to help elect Kamala Harris as the 47th President of the United States.

CaliforniaGov. Gavin Newsom: Endorsing Harris

In a statement made earlier this month, Newsom told the Los Angeles Times that he would not run against Harris if she became the nominee. CBS News’ sources indicated that was still the case following Biden’s withdrawal, saying that Newsom was "preparing to stand down," and that they did not believe he would challenge the vice president.

On Sunday afternoon, Newsom endorsed Harris writing, "With our democracy at stake and our future on the line, no one is better to prosecute the case against Donald Trump’s dark vision and guide our country in a healthier direction than America’s Vice President, Kamala Harris.”

Newsom is the only one of Harris’ potential challengers who is also not on the list of potential vice presidential candidates. Harris and Newsom are both from California, so the governor will likely have to wait out this cycle.

MarylandGov. Wes Moore: Will reportedly endorse Harris

Reports from both Axios and NOTUS indicate that Moore is expected to endorse Harris on Monday.

Moore’s statement on Biden’s stepping aside is probably the most personal and moving, noting that Biden is a man “deeply in love with his family, his country, and the promise of America.” It’s also the only message that extends thanks to first lady, Dr. Jill Biden.

MichiganGov. Gretchen Whitmer: Not running

Whitmer’s reaction to Biden stepping aside included this statement:

My job in this election will remain the same: doing everything I can to elect Democrats and stop Donald Trump, a convicted felon whose agenda of raising families’ costs, banning abortion nationwide, and abusing the power of the White House to settle his own scores is completely wrong for Michigan.

Whitmer certainly suggested that she would not be trying to take the lead role over the next three months, but her statement was far from definitive.

However, MichiganRep. Debbie Dingell appeared to confirm Whitmer’s position in a statement to MSNBC, in which she said that the governor was “not a candidate for any office this year.” That was backed up by a Bloomberg report in which a person close to Whitmer stated that Whitmer does not intend to challenge Harris for the nomination.

As of this writing, Whitmer has not formally endorsed Harris.

STILL IN FLUX

Kentucky Gov. Andy Beshear: Unknown

“President Biden will be remembered as a consequential president. Along with Vice President Harris, he led us through the aftermath of the January 6th attack on our Capitol and steadily steered us out of a global pandemic. … Now it is time for our nation to come together. We need to dial down the anger, rancor and noise, We have an opportunity to remember that we are taught to treat our neighbors as ourselves—and that we all each other’s neighbors.”

Beshear’s mention of Harris in his reaction to Biden ending his campaign would seem to suggest that he might be leaning toward an endorsement, but that’s not clear so far.

Beshear has managed to sustain high popularity while fighting against a Republican-dominated legislature in a deep red state, but compared to Whitmer or Shapiro, he may be less viable as a VP alternative simply because he may not been seen as boosting the ticket in a critical swing state.

Illinois Gov. J. B. Pritzker: Unknown

Pritzker offered one of the longest statements in reaction to Biden’s announcement. In it he praised Biden, but notably spent a good deal of space criticizing Donald Trump, noting his felony convictions, and saying, “I will work every day to ensure that [Trump] does not win in November.”

That could just mean Pritzker would work to support Harris. However, he’s one of the few potential candidates with deep enough pockets that starting a campaign with empty coffers might not be an issue.

Transportation Secretary Pete Buttigieg: Highly unlikely to run

That a member of Biden’s Cabinet would stand up against his endorsed vice president is on the very high end of highly unlikely. However, Buttigieg remains very popular and his name has been frequently mentioned a potential member of a Democratic ticket.

On Sunday evening, Buttigieg added his name to those officially endorsing Harris.

"Kamala Harris is now the right person to take up the torch, defeat Donald Trump, and succeed Joe Biden as president," he said in a statement.

WHO KNOWS?

Minnesota Rep. Dean Phillips: Calling for a “straw poll”

Dean Phillips is going to Dean Phillips. In this case, that includes reacting to Biden’s statement by saying that he got into the race “in the spirit of Paul Revere, not George Washington,” and finishing his thoughts on what may be the most critical political moment in decades with “Giddy up!”

Phillips then offered what seemed like an endorsement of Harris, calling her “talented, experienced, and well-prepared to beat Donald Trump and serve as our President.”

But an hour later, Phillips appeared to go all-in on a hackneyed plan for a popularity contest at the Democratic National Convention.

Conduct a straw poll among Dem delegates of potential candidates. Invite [Kamala Harris] and the top three other vote getters to a series of four, televised town halls w/audiences of delegates before voting at the convention.

If you’re wondering what that would look like, the top three vote-getters after Biden were Phillips, Marianne Williamson, and Jason Palmer—though all three were outpolled by “uncommitted,” which drew only 4.25 percent.

The best thing about this plan is that people are already very practiced at ignoring Dean Phillips.

During a Sunday evening interview with CNN’s Erin Burnett, Phillips predicted that Harris would win his little town hall contest, and insisted that “I do not wish to run.”

So what is Phillips actually supporting? Whatever will get him another 15 minutes in front of the cameras.
