Neither do you. Some are more corrupt than others. I guess it wouldn't matter to you if Hillary, Kennedy, Rangel and Reid ran the place, since they're all the same anyway, right?
Bingo! None of them are interested in making America better.
It's been 12 years since the "Republican Revolution" and where did it get us? Say what you will about Kennedy, Rangel, and Reid... at least they're honest about their socialist goals.
