I dunno? Why haven't republicans gotten a new candidate and asked the 70 time criminally indicted Trump as their front runner Candidate?
Seems like what Trump has been indicted for is much much much more serious than Joe's drug addict and slimey son and still no quid pro quo, or president Biden being bribed, nor for what he was allegedly bribed for, in any kind of evidence-based form....still innuendo on Republicans part.
If you get Trump out, NOW....then the DNC will force Biden to retire.... and Biden would likely welcome it...
And BOTH SIDES will have a shot at some younger candidates and newer ideas and those two, can duke it out.
