Wisconsin will likely be a must-win state for Democrats in 2020 given that President Trump flipped the state from blue to red, helping propel him to his surprise victory in 2016.

Biden also led the Democratic primary field in Wisconsin, according to the poll, with 28 percent of those surveyed naming him as their first choice. 

Sanders was the first choice of 20 percent of the same pool of respondents, while Warren was the first choice of 17 percent of respondents. 

Sanders had won Wisconsin the 2016 Democratic primary race with 56 percent of the vote. 

Meanwhile, the economy, likely a key electoral issue in 2020, elicited split views from voters in Wisconsin. Forty-nine percent of respondents said they approved of the president's handling of the economy, while 50 percent said they disapproved.  

The Marquette University Law School poll was conducted from August 25-29, 2019 among 800 registered Wisconsin voters. The margin of error is plus or minus 3.9 percentage points. Among registered Democrats, Democratic-leaners, and independents, the margin of error is plus or minus 5.3 percentage points.
