Maine Gov. Paul LePage (R) on Thursday went after a Democratic state senator by using a vulgar metaphor involving lubricant.

LePage told reporters that state Sen. Troy Jackson “claims to be for the people, but he’s the first one to give it to the people without providing Vaseline.”

LePage then walked away, later returning to explain his comment.

"That comment is not politically correct," he said. "But we gotta understand who this man is. This man is a bad person. He doesn't only have no brains; he has a black heart."

Senate Majority Leader Seth Goodall (D) denounced LePage's remark.

“We don’t condone that on the schoolyard. We don’t condone that at the kitchen table. Surely we don’t condone that from our governor,” Goodall told the Bangor Daily News. “This is just a really disappointing day.”

LePage's comments come after Jackson accused him of being "delusional" after LePage claimed that Democratic leaders refuse to work with him on the state budget.

It was revealed this week that the outspoken LePage, who is no stranger to heated rhetoric, ordered his staff to stop working with reporters from three of the state's major newspapers.

LePage is up for reelection in 2014. Rep. Mike Michaud (D) and independent Eliot Cutler are both challenging him.
