The former first lady is up by a margin of 50 percent of 44 percent with only 5 percent of the electorate undecided in Emerson College's poll. The poll shows similar demographic trends as in other contests, with Sanders leading with voters between 18 and 54 years of age but Clinton leading with older voters. 
Wisconsin is an important state for Sanders; he trails Clinton by more than 300 pledged delegates and more than 700 delegates once her support from party superdelegates is included. The state appears on paper to look favorable for Sanders — it's in the Midwest, it has a large college student population and a largely white Democratic primary electorate. Sanders has performed better in states that meet that criteria. 
But after Sanders's surprise victory in Michigan, Clinton rattled off wins in Ohio and Illinois, two Midwestern states he had hoped to win. 
There are 86 pledged delegates up for grabs in Wisconsin on April 5, which will be awarded proportionally based on results in congressional districts. The Emerson poll found that the candidates split the state's eight districts. 
Emerson polled 354 likely Democratic primary voters between March 20 and March 22 with a margin of error of 5.2 percent.
