The Marquette poll was conducted between Feb. 13 and 23 and included 1,000 registered voters in Wisconsin interviewed by cell phone or landline with a margin of error of plus or minus 3.6 percentage points.

Democratic primary voters view Sanders as the strongest candidate to beat Trump, with 34% holding that view. Republicans view Bloomberg as the strongest candidate, followed by Sanders.

Wisconsin’s Democratic and Republican presidential primaries are still more than a month away, on April 7. Before then, Democratic voters are set to decide in contests in South Carolina this weekend and in a number of Super Tuesday states March 3, where roughly one-third of Democrats nationwide head to the polls.

The Marquette poll shows a tight general election match in Wisconsin, with the Democratic candidates and Trump either receiving either the same level of support or sitting within a few points of each other. All general election match-ups are well within the poll’s margin of error.

This comes as Trump for the first time in Wisconsin has net neutral favorability, meaning just as many people view him favorably as those who do not. In previous Marquette polls, more respondents had viewed him unfavorably.
