a few things on this:
-don't underestimate Normal Whites - they will vote for biden over trump. they are not as loud as MTG chuds but there are more of them than the most rabid chuds. Normal Whites do not really give a shit about trans bathrooms, child sacrifice and retvrning to tradition. those are things for internet people with brain poisoning.
-the american electorate literally does not give a flying fuck about foreign policy or the rest of the world. biden's failures in project ukraine, genocide in gaza, the humiliation of the fall of kabul in 2021 - none of that means literally anything to the electorate at large. people like to think that maybe dubya was voted out over iraq, but that absolutely is not true, his problem was the economy (stupid). do not make the mistake of thinking that american voters give even the slightest bit of a shit about foreign policy. it is a distant number 15 on priority lists compared to the economy, immigration, etc.
-related to the above, for corporate interests, homeowners, people who own stocks the economy is doing fine. the line has gone up a lot under biden, especially recently. yes these gains are not evenly shared among the populace, but the people who gain them are far more likely to vote than poors anyway.
