Honestly i get both sides of this, like im in the UK and probably not going to vote Labour next election because theyve gone really out of their way to show the left how much they hate us, despite the fact its probably going to come down to Labour or reform, but the difference is here smaller parties are actually somewhat viable. So i think in the US it does make sense to vote Dem no matter what in the actual election, but put your effort into getting actual leftits on the ballot in the first place like Mamdani.
