I think a lot of them will be lazy and not vote. It is a lot easier to sit home than it is to be told to vote for Biden and then go out and vote for Joe Biden.
If they would vote for Biden or not depends on how strong their hate for Trump is.
They made the same threats in 16... and they voted to Hillary like the good little bitches they are. Leftists are wusses.. big talkers and actors in groups and no balls when they arent.
