A top-ranking Republican in the Maine state Senate said in an op-ed Wednesday that he is "embarrassed" by outspoken and controversial Gov. Paul LePage (R).

In the op-ed, Assistant Senate Republican Leader Roger Katz writes that LePage's antics are creating crises that legislators like him are forced to clean up.

"To me and many others, it is once again the unfortunate tone being set by our chief executive," Katz writes. "His use of vulgarity and schoolyard taunts to demean his Democratic opponents. His failure to offer real apology. And then his insulting of Republican legislators who choose to disagree with him.

"As a lifelong, proud Republican who was overjoyed to see a Republican elected back into the Blaine House three years ago, I have one thing to say. I am embarrassed."

LePage last week said that a Democratic state senator was "the first one to give it to the people without providing Vaseline." And that was hardly the first time LePage's outspoken nature has caused a stir.

LePage is up for reelection in 2014 and is considered very vulnerable, but in recent days has suggested he might run for Congress instead.
