As establishment Republicans look for ways to slow Donald Trump’s relentless march toward the party’s presidential nomination, Wisconsin’s winner-take-all GOP primary contest on April 5 offers some intriguing possibilities. In a statewide Emerson College poll released today, Texas Senator Ted Cruz is not only leading Trump 36% to 35% in the upcoming primary, but Cruz is only trailing Hillary Clinton by one point in a hypothetical general election matchup, 46% to 45%. In contrast, Trump is trailing both Clinton and her Democratic rival, Bernie Sanders, by the same 9-point margin of 47% to 38% in a potential general election match-up.

In the Democratic primary, Clinton leads Sanders by 6 points, 50% to 44%, with 5% undecided. Wisconsin’s demographics bode well for Sanders, who has enjoyed his strongest wins in states with a low percentage of minorities and lopsided support for him among young voters. He leads Clinton 67% to 29% in the 18-34 age group and ties her at 48% among voters 35-54. As in other primaries Emerson College has polled, he trails her by large margins with older voters: 63% to 31% (ages 55-74) and 73% to 19% (ages 75 and up). Less than 10% of the state’s Democratic voters are African American or Latino, groups that have supported Clinton very heavily in other states.
