Via The Washington Post, news that will reverberate across Washington:
DeMint, a staunch conservative who often clashes with party leadership, was reelected to a second term in 2010. He will depart before the new Congress is sworn in next month. “I’ve decided to join The Heritage Foundation at a time when the conservative movement needs strong leadership in the battle of ideas,” DeMint said in a statement. “My constituents know that being a Senator was never going to be my career.”
