The poll, which comes after a Democratic primary debate in Milwaukee this month, has Sanders narrowly leading Clinton by 44 percent to 43 percent, well inside the survey's margin of error.

The Vermont senator trailed Clinton by a 9-point margin in Wisconsin, 50–41 percent, in November.

The poll also finds Sanders matching up better than Clinton against top Republicans in hypothetical general election races in the Badger State.
