That...should still place you firmly in the democratic party and certainly not inspire you to vote for Trump. Pretty much everything the Biden administration is trying to do will improve the lives of exactly those people.
If I believe immigration, free trade, and internationalist foreign policy have harmed the American worker, why would I support a party favoring them? Those are my three big issues.
My votes in presidential elections:
04 Kerry
08 Obama (supported Kucinich early in the primaries)
12 write-in
16 Trump (voted Sanders in the primaries)
20 Trump
Biden hasn't been as bad on those three issues as he campaigned, anyhow, which is why I'd consider him over a non-populist republican in 2024.
