We really thought we were done hearing about big shake ups in the Republican Party of Minnesota. What with Tony Sutton’s abrupt departure last week and then the discovery that the GOP is close $1 million in debt from campaign and operating expenses and recount costs the party thought it didn’t have to pay. But now GOP Sen. Majority Leader Amy Koch has resigned amid accusations that she had an “improper relationship” with a staffer. Koch, who is married, has neither confirmed or denied the allegations, but was confronted directly about them before her voluntary resignation.

Even without the scandal of accusations, the resignation leaves the Senate Republicans with the task of filling her roll on short notice (Sen. Geoff Michel of Edina will be interim leader). Minnpost takes a look at how the replacement process for a new Senate Leader might shape up.
