Massachusetts Gov. Deval Patrick (D) ruled himself out of a 2012 challenge to Sen. Scott Brown (R-Mass.), but predicted there won't be any shortage of Democrats in the running. 

“If there are as many candidates as have indicated they are interested, there will be a contested primary, and I will stay out of that ... but when it comes to the general election, I expect to be very involved," Patrick said at a luncheon with journalists in Boston on Thursday. 

Patrick, who won a second term in November, insisted he won't be one of the candidates in the crowded field.

"I am certainly going to be involved in conversations with would-be candidates and have been already," Patrick said, according to the Boston Herald.

Patrick said he's already talked to "a few" interested candidates but didn't reveal any names.
