Trumps rating was always fairly low (by historical standards). But so what? The statement I made referenced TODAY - which is that even with Biden's sinking popularity, Kamala (his theoretical replacement) is even lower than Biden - AND surprisingly, even lower (by a smidgen) than Trump is today. Historically, except for Chaney, VPs are usually better on the favorability section because they dont have to make hard calls.
Point is, if Biden is still coherent by 2024 and runs, Trump beats him with today's mood. If Kamala runs instead, I think she does even worse than Joe as she really isnt well liked, even within the Dem party. So Dems have a choice to dump her and find a better candidate or hope that Reps take over both houses of congress and do stupid things that piss off the broader swath of voters before the Presidential. Fortunately for Dems, I rate this scenario as a substantial probability of occurrence.
