Gotta love the legions predicting that Wisconsin and Iowa are going to be R trends despite the evidence. Minnesota is likely to trend R while the opposite will be seen in Wisconsin. This is because a greater percentage of MN's population exists along the shores of Superior, a historically D area that is clearly going R.
PA and MN show much more evidence of a shift toward the GOP than OH and WI, do it is plausible that within 10 years each will surpass in swing state status (as seen on map below).
Same goes with NH and ME. Legions predicting that they will trend R over the next decade despite opposite evidence.
As for a "more libertarian GOP," new social issues are always on the horizon. They do not go away.
I think that in 10 years, we will be looking at something like this:
90% = safe
50% = likely
30% = lean
gray = toss up
And without shading to make it cleaner to read:
