Apparently, the Campaign is "testing" how Kamala would do against Trump. I'm not sure that would be good for her, though. Or, rather, her political future. Is it worse to be a running mate on a losing team, or the principal on a losing team? (I genuinely don't know the answer to that.) In the USA, she would have an uphill fight because she is female, and a dual-minority. Shouldn't be, but that's the reality. The fight would be made tougher if she takes the reins with less than four months to go.

The survey, which is being conducted this week and was commissioned by the Biden campaign’s analytics team, is believed to be the first time since the debate that Mr. Biden’s aides have sought to measure how the vice president would fare at the top of the ticket.

...

As the White House and the Biden campaign try to project a unified front, some of their supporters are engaged in a tough assessment of who should top the ticket.

Apparently the next "judgment" will be this week when Biden goes to the NATO summit.

But, yeah, the NYT blows sunshine up my left-wing butt...I'm all aglow with the positive spin on Biden. (In case it wasn't obvious, that was sarcasm.)
