Dems win OK but not:
AZ
CT
MD
NH
RI (!)
TN
I can't see this happening. If Trump's economic policies are so bad that Oklahoma, a state with zero Dem Senators or Representatives, a state that hasn't had a single county vote for a Democrat in a Presidential election since 2000, flips, then the GOP sure as hell isn't winning any of the six states I listed above.
You do realize gubernatorial elections are not the same as presidential elections, right?
I'm well aware it's significantly easier to flip a state in a gubernatorial election than a presidential one, but that's not the point. Point is, Oklahoma is incredibly conservative, probably a contender for the most solidly Republican state in the nation. Obviously Dems actually have a shot in the gubernatorial election there whereas they have no shot in any presidential election there, but the point is that Oklahoma is almost uniquely conservative.
