Basically, a certain group of elite rich people/ organizations are pushing Biden to step down after the debate.
If they were serious about wanting Biden to drop out then they should have done so 6 months to a year ago, because they were backing Biden up to a few weeks ago.
Due to requirements surrounding presidential candidates being listed on ballots in certain states is the reason why Biden will be on the ticket.
If Dems try to switch their candidate now the R's will challenge.
