bur maybe not if Biden did a deal with Robert Kennedy Jr...
I think there are a large number of sensible Americans who can't stand Trump, even Republicans, who resent how he has taken over their party. There are a lot of them I believe who feel they have to vote for Biden, or cannot bring themselves to. Rather like the Boris/Corbyn thing here and similar to when Trump was up against sanders. The democrats need a young(er), charismatic candidate, but it may be too late now with less than 5 months to go.
