President is two jobs. One is policy driven. One is being a leader. All president’s have to do both, but arguably the latter is more important as president’s can leave policy to aides and congress (and formerly the federal agencies, but that’s gone now). The president is a communicator. Yes most voters like Biden policies, but they don’t know they are Biden policies because Biden does not communicate that. In fact, in many congressional districts the Dem candidates are outperforming Biden while running on the same policies. You can’t blame voters already burdened with living in this capitalist hell hole for not devoting hours into researching candidate policies.
In presidential politics, at the end of the day the buck stops with the candidate. Campaign aids and paid advertising and surrogates on TV can only do so much. You need the candidate to deliver, to speak directly to the voters, to make the case for why voters should choose them and their policies over the alternative. Biden is incapable of that.
It’s Bidens fault.
The worst possible time would be this fall. Imagine if Biden had that debate performance a couple of weeks before election? At least if he drops out now he can be replaced. Problem is, if he stays in, what are the odds he’s going to have another episode of “jet lag” or a “cold” or whatever excuse they are using now? Unless they keep Biden in a bunker till November, chances are good he’s going to have another episode and freak out swing voters right before votes get cast.
