The elephants in the room will be issues like Wars (e.g. Russia/Ukraine, Israel/Hamas), abortion, inflation, and immigrants gaining voting rights, Independents jumping into the election waters along with the fact that a few other key Democrats still have not stepped up to the plate to prepare to take out Joe Biden as if they're more afraid of Trump.
The latter is important because Republicans are becoming uneasy with the thought of a Biden/Trump repeat...too much chaos that will bring to the GOP. More so for Republicans than Democrats.
Ohio and Kentucky recently opened a path to an election victory for the Democrats. The question is do they need Joe to be driving that car towards a possible showdown against a "criminally convicted Trump" by election time ???
Simply, right now for someone to wish for Joe Biden to fail is just another
Joe Manchin wannabe without a suitable alternative to take on Trump. Thus, find a strong alternative first and then get rid of Joe Biden.
