his point was about using bourgeois parliaments as a platform for revolutionary agitation and exposing their limitations as a part of a workers movement. it was not about supporting bourgeois parties or treating elections as the primary terrain of struggle. invoking that in support of voting for democrats is a distortion of what the polemic was about.
And for that you need to build a little foothold. Which we lack in many places federal to local.
this is exactly why i prefer to devote my energy to making sure that my neighbors can eat and protesting against democrats capitulating to republicans. i don’t see those problems going away after a successful election, even when democrats have a supermajority they find a way to do what republicans want.
And you would have more room to do that with mid dems too.
