Unfortunately, Biden’s approval numbers are only marginally better than Trump’s. Though I think Trump’s numbers can’t improve while Biden’s can, but even if they do, that’s not enough to translate into votes. Coupled with the fact that Trump has better odds of winning with a lower percentage of the popular vote, I think it’s fair to be upset with the situation.
I suppose the only two advantages Biden has are that his name is known and that the manner in which he is hated may be more tepid than the manner in which Trump is hated. Though by the same token, the manner in which he is approved of is almost certainly more tepid than the manner in which Trump is approved of.
No matter what candidate the Dems run, at this point they’re likely going to have to rely on anti-Trump sentiments to call voters to action. I don’t think they can build a candidate who is an answer to Trump in the time remaining run up until the election.
