Sen. Jim DeMint (R-S.C.) is a loner in the nation's capital and he's proud of it.

During his speech to the Conservative Political Action Conference on Thursday, a smiling DeMint said, "I did not come to Washington to make friends and so far I haven't been disappointed."

DeMint isn't just playing to the crowd. He has infuriated members on both sides of the aisle with his crusade against earmarks and other government spending.
