They like Joe Biden as he is now, the former VP to a President they strongly like and admire.
If/when he runs for President as championing the pre-2016 status quo, and inevitably has multiple gaffes, they aren't gonna like him as much. He may not implode but his numbers are gonna come down to Earth pretty fast.
Additionally, he's out of step with the Democratic Party on multiple issues that the party is undeniably starting to moving left on (primarily economic issues). If Biden ends up winning the nomination and then wins the presidency, he'll rightfully face a lot of scrutiny from the left for not being progressive enough, if at all.
And on top of that, Biden seems a very likely target for #MeToo accusations, either sincere or GOP-generated. Both from
Thomas' confirmation hearings and the regular appearances of "
Creepy Uncle Joe".
He would be a very poor choice for nominee. Fortunately, I doubt he's running.
