Everyone please read "Left-Wing" Communism: An Infantile Disorder for some quality Lenin dunks on ultras with an inflexible tactical line on elections and stuff.

The American system is incredibly undemocratic and inflexible though, and Americans are incredibly brainwashed about it, so I think in the US most of that value comes from propaganda.

Even the Sanders stuff isn't completely without value when you consider how much easier it is now to break through on the US not being a democracy to a section of Sanders libs, and the effect this had on the old sub. (though that's only a first baby step to capitalize on)
