It’s not changing any minds. People might get more and more tired of his sh**t, and that probably accounts for what I expect to be a 2-3 point swing against him in a rematch. I think part of that swing would include older conservatives aging out of the electorate
On the contrary, Biden has older support, specifically Biden's own age cohort.
Basically those who first voted in 1964 voted by majority for Biden and for Democrats in 2020/22.
It's middle aged people where Republican support currently peaks.
