Next year it'll be 20 years since the Minnesota GOP got over 50% in a statewide election. That has to be a record amongst all states for either party failing to get over 50%. (Yes, even with Utah and Idaho, a Democrat got 56% for State Controller in Idaho in 1998 and 52% for Attorney General in Utah in 1996.)
When I saw the title for this thread, the Minnesota GOP was what immediately came to mind. Even in 2010, their biggest win was picking up a House seat--a seat they lost two years later. For a state that so many people insist is "moving to the right," the state party is incredibly incompetent.
For what it's worth, the Michigan Democratic Party blew MI-01 last year, along with
all of the court nominees they were backing, Proposition 2, completely failed to recruit a candidate for MI-11, and made marginal gains in the state legislature in a Presidential election year. Their leadership needs to do some serious reflection before 2014.
