Eugene Debs was an out and out socialist, who led the most violent strike in US history. You can make an argument that he didn't make it violent -- that was the Pinkertons -- but he didn't get tossed in jail because he ran an opposition party a la Navalny. He's not the boogyman that some would make him out to be, but he didn't pull punches, either. Got 3% of the US vote behind bars, too.
