At least they talk about stuff that the post-industrial working class care about. Like, Trump may not succeed in bringing back manufacturing, but the Democrats never even talked about it (even though Biden did a bunch of good stuff there).
And fundamentally, the coastal states don't have enough votes for the Democrats to win a majority, so they need to start figuring out how to win in the rest of the country.
Personally, I'd have removed the filibuster in the Senate to fix gerrymandering, as that makes the elections much fairer and takes away the ability of state legislatures to make ridiculous boundaries that are always gonna vote for one party. Hilariously enough, it was the old school Republicans who started this, which has lead to them being replaced by MAGA loyalists.
