Minnesota, despite the noisy assertions of the Trump team, was always going to be a very heavy lift for him in this campaign. Back in November, I wrote with John Halpin:
"The Democratic candidate in 2020 will seek to keep the Democratic streak going, while Minnesota, given the closeness of the 2016 result, will be on the short list of states that Trump targets to try to expand his coalition. This may be difficult; he is quite unpopular in the states, with a current negative net approval rating of -15.
Nonwhites were just 11 percent of Minnesota voters in 2016. Asians/other race were the largest nonwhite group at 4.5 percent and they supported Clinton 50-36 percent. Blacks were 4.3 percent of voters and went heavily for Clinton by 90-6 percent. Hispanics were just 2 percent of voters and supported Clinton 61-30 percent. In addition, white college graduates, an unusually large 36 percent of voters, backed Clinton by 22 points. The bright spot for Trump was white non-college voters, 54 percent of the voting electorate, who favored him by 21 points....
The logical strategic choice for Trump would be to enhance his 21-point margin among white non-college voters from 2016. A 10-point margin shift in Trump’s direction among this demographic group would result, all else remaining the same, in a 3-point GOP victory. A more difficult target would be to reduce his deficit among white college voters by 10 points; that would result in a narrow 1-point victory for him."
Well, none of that is happening for Trump. That last two polls of MN, by New York Times/Sienna and CBS/Yougov, each have Biden ahead by 9 in the state. Not only has Trump failed to increase his 2016 margin among white noncollege voters by that 10 point target, he has failed to increase it at all, down by 5 points in the CBS poll and cut in half in the New York Times poll. And among white college voters, he is losing by several points more than he did in 2016 according to both polls.
Sure, it's still possible Trump could take the state. But right now, it looks like a mirage.
