I’m Karen Tumulty, and for Round 63, we’re checking back in on who will share the ticket with Joe Biden. Since our last ranking in March, would-be veeps have done some vigorous campaigning in public and behind the scenes, and Biden promised he’ll pick a woman. (Sorry, Cory Booker.) But — which one?

The Commentary

In some ways, the least significant aspect of Biden’s choice of a running mate is figuring out who is most likely to help him win in November. Far more important is the question of who can best help him govern — and who is most qualified to take over as president herself.

Biden would be the oldest president ever to take office, and he has not discouraged speculation that he would serve only one term. Should he be elected this fall, whoever he picks as VP would automatically be in the lead position to become this nation’s first female president. And even if Biden loses, his running mate could emerge as the most influential figure in determining the Democrats’ next moves.

Biden understands all this. He also knows that his own résumé was the main reason he got the nod from Barack Obama in 2008. Biden was on the ticket to answer qualms that a freshman senator wasn’t prepared to handle the presidency.

So who will be Biden’s Biden? There are talented political newcomers out there, notably Stacey Abrams, but my hunch is that experience will once again be the Democratic nominee’s overriding consideration.

Most obvious among the leading contenders are the three female senators who opposed him in the primaries. Biden’s heart probably leads him toward Amy Klobuchar. (It’s now known that Klobuchar has been asked to undergo the vetting process, and it would be surprising if she weren't.) But Biden also faces significant pressure to pick an African American, which gives Kamala D. Harris an edge. Selecting Elizabeth Warren would excite the party’s progressive base.

In the early handicapping, I don’t think the governors are being talked about as much as they should be. As a group, their political stock has skyrocketed during the pandemic. I’ve written before why Gretchen Whitmer (Mich.) should be on Biden’s shortlist. But she is not even halfway through her first term, and she cannot afford to be distracted from her day job now, given Michigan’s covid-19 toll. Rhode Island’s well-regarded Gina Raimondo would also be a solid pick. But if Biden goes looking outside the Senate, keep your eye on New Mexico Gov. Michelle Lujan Grisham.

From the Annotations

If Biden is really planning an FDR-style presidency, as he clearly wants voters to believe, then picking Warren as veep would telegraph he’s dead serious about it.
