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?
Ah, the old trend line fallacy. By that same logic Virginia would vote identically to New York in 10 years.
...and no Republican has won in 8 years, and that no Republican has won over 50% in in 22 years. So going from that to completely unwinnable for any Democrat in a statewide in only 10 years, when the state's non-white population is rapidly increasing (which didn't happen much from 1984 to about 2000) would be one hell of a steep slope.
