PORTLAND, Maine (AP) – The Democratic challenger to Maine Governor Paul LePage has announced that he’s gay. Six-term Congressman Mike Michaud says he needed to address his sexuality to counter “whisper campaigns, insinuations and push-polls” that raised questions about his personal life. Michaud wrote in an op-ed provided to The Associated Press and two Maine newspapers that he wanted his political foes to know that, in his word, “I am not ashamed of who I am.” Michaud didn’t identify who he thinks was behind the whisper campaign. The announcement adds intrigue to a tight three-way race with LePage, the Republican incumbent, and wealthy independent Eliot Cutler. It’s unknown what impact, if any, Michaud’s disclosure might have in a state where voters approved gay marriage a year ago. Michaud supported the measure. There are no gay governors in the United States.
