I dispute that MN is a Dem state.
Let's see, we have a majority of the Congressional delegation, almost veto-proof majorities in both houses of the legislature, every downballot statewide office holder, and haven't voted for a Republican for President since 1972. I think that sounds pretty strong Dem to me.
Also, she had a big win in an open seat against a flawed candidate (yes, BRTD, I know that some of us thought he was strong) in a perfect year for her party.
And won by 20 points. That doesn't happen by accident. It's bigger than in Ohio, where the GOP was suffering a massive meltdown. She's a great campaigner who has far more widespread appeal and would've easily won the seat in anything other than a 1994 scenario.
