The fight over allowing same-sex marriage last year could claim its first political casualty as a GOP legislator faces an insurgent challenger from his own party over his support for the legalization effort.
Rep. David FitzSimmons, R-Albertville, is immersed in a bitter and increasingly personal battle with newcomer Eric Lucero, a technology manager and Dayton City Council member who has made FitzSimmons' support for same-sex marriage the centerpiece of his campaign.
The defining battle will come Saturday, when GOP activists gather to endorse a candidate for the House seat. FitzSimmons says he will abide by the party's endorsement, creating a make-or-break moment for the first-term legislator.
"Losing is a distinct possibility," he said earlier this week. "I think I have a solid shot to win, but anything can happen."
FitzSimmons was among just four House Republicans who broke with their party to vote for legalization last spring. Of those four, one is not seeking re-election. The others have raised significant money and so far withstood challenges from within.
Ousting FitzSimmons would be a strong statement from the conservative flank of the GOP and hand a rare win to opponents of same-sex marriage after a string of high-profile defeats in Minnesota.
"It's kind of sad when we are in this place, where constituents have to act to find someone who better represents their values," said Autumn Leva, a spokeswoman for the Minnesota Family Council, which is working to defeat FitzSimmons.
Lucero, who repeatedly turned down requests for interviews, has framed himself as a crusader for traditional family values. His website features a picture of him with a lion in the movement, U.S. Rep. Michele Bachmann, R-Minn.
