From the Washington Post’s Marc Thiessen:
It is this success that has led DeMint, after much contemplation, to decide that he will not endorse anyone in the 2012 GOP presidential primaries. “I want to announce that I am very unlikely to endorse a candidate in the presidential race,” DeMint told me in an interview this weekend. The most disappointed GOP contender may be Mitt Romney, who received DeMint’s endorsement in 2008 and could have used the senator’s support to woo skeptical conservatives this time around. Why did DeMint decide not to endorse Romney again? “It’s a different race, different people in it, different time for our country,” he said, adding, “I would be very comfortable supporting any of … [our candidates] for president.”
