I think a lot of voters were fooled (or foolish) into thinking that Trump would limit himself to go after other people; he got a higher percentage of minority votes in 2024 then prior elections. That's not good but the mask is off and I think Trump has lost a lot of those voters.
It's also hard to quantify how much the pandemic and inflation moved some voters away from Biden/Harris.
I think Dems will win big in the next election. The question is how long this lesson will last with voters.
