HE'S NOT A REPUBLICAN:

In an upside-down version of a traditional campaign, the Republican front-runner is immensely unpopular in the reddest part of the state -- the outer suburbs and exurbs that ring Milwaukee.

These are the party's bedrock counties: Waukesha, Washington and Ozaukee. They typically dictate the outcome of GOP primaries like the one Wisconsin will hold for president April 5. And in fall elections, they're arguably the best-performing Republican counties in America.

But GOP voters in these counties dislike Trump by a very large margin. In extensive polling by the Marquette University Law School, 25% view him positively and 64% view him negatively, for a "net favorability" -- in his own party -- of "minus 39."
