We can argue about shades of left wing and or centrism until the cows come home. Compared to Project 2025 I frankly don't give a fuck what Kamala Harris' policy platform is. Donald Trump, for the sake of the whole Western world, cannot be President again.
We just had this in the UK. After the "here's what you could have won" edition of the Labour Party under Corbyn which was "left wing" by our standards (but barely left of fucking centre as far as Europe is concerned overall), Starmer's Tory-lite Labour is a disappointment but compared to the erratic and sometimes borderline evil governance of the Conservative Party it isn't a contest.
