Minnesota Senate Majority Leader Amy Koch on Thursday resigned from her leadership post, shocking Republican legislators and State Capitol leaders.
"I never thought that I was doing this for a lifetime," said Koch, R-Buffalo, adding that she will serve out her Senate term but not run for re-election next year.
"It was gratifying. We did wonderful things. It was exhausting. I think you just know when it is time to let someone else have the reins, and it's time," she said.
Koch said her resignation as majority leader stemmed from her decision not to run for re-election.
"We cannot afford a lame-duck leader in negotiations next session, which is why I am resigning from my position as majority leader," Koch said in a letter addressed to "friends" and released on Thursday afternoon.
She had led the Senate for only a year. Republican legislators said they had no inkling she was planning to leave her post. Now they will scramble to elect a new leader by the end of the year, just a month before the 2012 session begins.
Koch's abrupt decision follows closely the sudden resignation of Minnesota Republican Party chair Tony Sutton. Although unrelated, both change the party's path going into the tough 2012 elections.
"Obviously, any time there are significant changes in an organization, challenges result," said Assistant Senate Majority Leader Dave Thompson, a Lakeville Republican. He said he was "blindsided" by Koch's decision.
