Analysts say today’s (Tues) presidential primary in neighboring Wisconsin could determine whether Republicans have a contested national convention this summer. Donald Trump in Superior yesterday blasted chief rival Ted Cruz and pledged changes if elected president. Trump said, “We use political hacks to negotiate the biggest deals with these massive countries. Those days are over. We’re going to make great trade deals, and they’re not taking our jobs any longer.” In Madison, Cruz argued the race is going his way. “What we are seeing happening in Wisconsin is the unity of the Republican Party manifested,” he said. On the Democratic side, a win for Bernie Sanders in Wisconsin would increase his momentum, but analysts say it’s still unlikely he could defeat Hillary Clinton for the party’s nomination.
