Biden leads Trump by 9 points in Wisconsin: MU Law Poll

Former Vice President Joe Biden had a 51-42 percent lead over President Donald Trump among registered voters in the Marquette Law Poll released Wednesday.

The margin of error for the head to head matchups was 3.9 points, after polling 800 registered voters.

Sen. Bernie Sanders, D-VT, had a smaller 48-44 percent lead over Trump. Senators Kamala Harris, D-CA, and Elizabeth Warren, D-MA, were tied with the current president in the polls.

This is the first MU Law Poll this presidential cycle to show head to head matchups. Biden also came out on top in a survey asking Democrats, independents and independents leaning Democrat, to pick their top choice for president. Biden took 28 percent of that vote,  compared to 20 percent for Sanders. Warren was the top choice of 17 percent. Then there was a drop off with Pete Buttigieg at 6 percent and Harris at 3 percent.

"Biden at this stage with a noticeable lead, but it's early," Poll Director Charles Franklin said. "And this is the first time we've looked at this question during 2019. So let's stay tuned and watch that through the fall as the Democratic primary shapes up on the one hand, and as the presidential race begins to get more focused."

Franklin says polls will now come out much more frequently on the way to the election. The Wisconsin primary is April 7th.
