The Senate has voted on three pieces of legislation today that required 60 votes–to raise the debt ceiling to $14.3 trillion, to reduce the deficit by establishing five-year discretionary spending caps, and Ben Bernanke’s confirmation–all of which interim Senator Paul Kirk (D-MA) has voted on.
Of course, the Republican party doesn't care. The reason is because the Senate doesn't represent the people's interests anyways, but instead the interests of the political parties. The 17th Amendment allowed the Senate to come under control of the political parties and their special interests, and that's all it represents now.
Repeal the 17th Amendment and restore the Senate to its Constitutional role of limiting the federal government.
