This poll number shows something very important about the Tara Reade allegation

Opinion about whether the accusation is true is very, very divided. Roughly 4 in 10 (37%) — say the allegation is “probably true” while 32% say it’s probably not true, and 31% have no opinion.

Which isn’t great news for Biden. Except that when you dig into the numbers one level further, you find this: Among the group that says the accusation against Biden is probably true, he still wins 1 in 3 of their votes. (President Donald Trump gets 59% among that group.)

What that means — at least at this relatively early stage in the general election race — is that there is a decent chunk of voters whose dislike for Trump or support for Biden overrides even their belief that Reade is telling the truth about Biden. They so want Trump out that they are supporting Biden even in spite of believing the unproven (and denied) allegation that he sexually assaulted a woman in the early 1990s.
