The LA-AR-MO-IA-MN stack is going completely like the TX-OK-KS-NE-SD-ND one, and within 10 years, Democrats will not have any non-inner city seats in any of those five states and will not be competitive in any statewide elections.
And the signs of that in MN are?
The fact that it has gone from the most Democratic state in the nation in 1984 to a swing state with a PVI of D+2 today?
But it has a Democratic Governor and two Democratic Senators and has voted Democratic every year since 1984! A similar reason to why West Virginia was easily won by Kerry in 2004, and Obama in 2008 and 2012.
