Who controls Congress? Members of Congress get money from various interest groups (and anybody who thinks that doesn't effect how they vote is plain nuts), but that doesn't constitute control. In the final analysis, the voter controls Congress . It is unfortunate that not all voters are fully informed or think about the ramifications of what they are doing, but that's something that will never be cured. Vote! Get registered, and then vote! I read this morning that some 35% of eligible voters in the US are not registered. I guess that this uninterested, uninvolved or disgusted 35% are the ones who really control Congress. I have to think that those who fail to vote really forfeit their right to complain about the outcome.
