Minnesota was 53% to 45% for Obama in 2012. That's 225,000 votes. They was a 10% split in 2008. It was democrat in Bush's re-election. It was democrat in Bush-Gore.
I just don't see where these polling numbers are going to lead to that type of change in voting record or turnout.

Minnesota is Hillary's. And any republican that thinks this election process is going to be that type of reversal of history is delusional. You guys are REALLY underestimating Hillary's ability to campaign. She's getting very close to 50% of the overall vote MINIMUM. And that's only if the Republicans put their very best candidates forward that can win in very specific, moderate states.
This is a map showing every state that won BY AT LEAST 5% points over their opponent.

There were only 6 states that had election results within +/- 5% of each other and whatever Republican runs has to win almost all of them: FL, NC, VA, OH, CO and NV
What's more dangerous is if Hillary selects Mark Warner, a young good-looking white male from Virginia, and wraps that state up and wins all the other states Obama won by +5% or more in the last election, she's at 270 electorate vote and it's over. The Republicans could win FL, OH, NC, CO and NV and still lose.
I personally don't see how it's going to happen. The voting records of people just don't swing that much anymore. We've polarized the whole process so much that the "undecided" isn't really as "undecided" as you think. They end up voting for the same reasons for the same type candidates.
None of the candidates out there is going to change how people voted last time by that much. Everybody talks about "turnout" but that is just bullshit. People who vote, vote. People who don't, don't. And when elections are popular, voting percentage increases for BOTH SIDES. Voter turnout has been 56%, 57%, 55% the last three cycles. That's the new norm in today's social media and info age. That's not going to change.
Republican's need to realize this is a very uphill battle. They to respect their opponent's ability. They need to realize people aren't going to turn up to vote "against Hillary" and they need a candidate to "Vote For". They need to get a candidate that can win FL, OH, VA and NC. East coast, moderate republicans, moderately religious. Not deep south rednecks. Not midwest evangelicals.
Carson might win VA and NC due to being black and kind of baptist religious-like (and that's a huge stretch). He'll lose FL and OH.
Trump might win OH. He'll lose FL, VA and NC.
Cruz might win OH. He'll lose the rest.
Rubio is really the only one that has a chance of sweeping those states. And that's the only chance at winning the white house.
