And in those places where Americans are not stupid enough to vote for these people, or want to vote them out, these people have managed to stay in office by gerrymandering to the point where votes cast against them simply don't matter.

Every few years, the party that's in charge of an area gets to draw up the voter maps, so that its easy to craft local maps so that they awlays win in certain districts.

Anyway its a comlicated setup used to make certain peoples votes simply not matte. Voters being culled from voter rolls also works to keep them in office, so they literally cannot be voted out.
