That polling has been out for a few days. I saw a poll where he was polling even with Kamala, putting them both 2 or 3 pts behind Trump. They both will lose to Trump. From the way the governors meeting was described, it sounded like a cheerleading party. This just sounds like more covering up and hoping for the best. Foreign leaders are not going to have any kind of confidence in his abilities, and he's still going to have problems battling against constant attacks on his mental fitness every day, even if he wins office.(Which he won't.)
Excerpt from headline article on CNN,
"Biden’s comment during Wednesday’s meeting left several of the governors in the room frustrated, sources told CNN, and is one of the reasons that some of the participants have been rankled by the statement of loyalty and enthusiasm from them distributed by the Biden campaign on Thursday."
Don't be so certain yet. They just got the big cheerleader from that meeting, out for the press conference. Doesn't yet show if the other governors who were aggravated that the campaign was trying to cover them up are going to speak out about this. This is just more cover by the campaign, & does not address the issue.
