New Jersey Gov. Jon Corzine (D) told Andrea Mitchell this afternoon on MSNBC that he will indeed run for governor this year.

"I am going to be running," Corzine said. "I think that's the first time I've said that on television, so you're breaking news. Although, everybody knows that we filed our papers in front of the primary deadline. We're actively pursuing building our organization and preparing to run."

A Monmouth/Gannett poll out today finds Corzine trailing former U.S. Attorney Chris Christie by 4 points -- the latest in a long run of disappointing numbers for Corzine.

The governor said property taxes, a local issue in the state, were a drag on his numbers there, and that the nation's dismal economy hurts most incumbents around the country.

"It is a time when people are very uncomfortable, and if you're in office, some of that is going to rub off on the incumbent," Corzine said. "I am quite hopeful that working as a partner with the White House, we'll be able to see some of that change come about here in New Jersey, and we'll see a better outcome in November in those polls."
