I think SocDems had a historically progressive role in the hyperreactionary landscape of the US. Before Bernie, "socialist" was a pejorative. Now it's a lot more complicated, we can actually talk about socialism now without being written off and liberals are calling themselves socialists to win elections. Also, in Iowa especially I can use Bernie getting ratfucked out of the race to pull people away from Dems, because they so obviously destroyed the caucus to hand a win to a loser nobody like Mayo Pete.

They've outlived their shelf-life, though. Mamdani is now actually to the right of where a lot of USAmericans are on police and on Israel; he holds progress back every time he pointlessly compromises with Democrats and the NYPD and the Zionist lobby
