They're terrible. Nevermind for a second that they buy the votes of idiots. What startles me is that the more money you and your campaign have, the more ads you can run and the more your message gets spread. It's unfair. I'll just run some figures by you guys:

A quarter of America's Senators are millionaires, as compared to the less than 1% of America's public who is as rich.(link) A third of the Senate races and more than 95 percent of the House contests were won by the candidate whose campaign cost the most money in the previous elections. (link) 43% of the freshman Congressmen from 2002 were millionaires and in the term before that, a third of them were. (link)

Is that representing the needs of the average person? The biggest campaign and the fattest wallet seem to win out too often.
