Joe Biden leading Donald Trump 47-43 in Wisconsin: MU Law Poll

MILWAUKEE (CBS 58) -- With just 54 days until Election Day, Joe Biden leads President Donald Trump among registered Wisconsin voters by 4 points at 47-43 percent, according to the most recent Marquette University Law School Poll.

Biden's lead changed by only one point from August, when he led 49-44 percent, despite two party conventions, the events in Kenosha and visits to the state from both candidates.

“Lots going on in the world, but it didn’t shift opinions very much," MU Law Poll Director Charles Franklin said. "It didn’t shift votes, and it didn’t shift very many attitudes.”

The unchanging attitude includes protests against police brutality.

After a significant shift in attitude from June to August, the events in Kenosha had almost no effect on voters. Forty-seven percent of voters approve of protests against police brutality, against 48 percent who disapprove. In August, 48 percent approved of such protests and 48 percent disapproved.

“There was already a lot of messaging going on about the protests and Black Lives Matter, and that sort of set the stage and shifted opinion, and once it had shifted, adding Kenosha didn’t really have much more effect,” Franklin said.

This poll marked the first look at voter opinion on Kamala Harris as a vice presidential candidate. She is viewed 38 percent favorably and 37 percent unfavorably among registered voters. Mike Pence is viewed 39 percent favorably and 46 percent unfavorably.

“The fact that she’s about even in favorability, a point positive, is a pretty good start for a vice presidential candidate,” Franklin said.

Trump is doing better in the Marquette Law Poll than many others polling the state recently. Most show Biden with an eight to nine point lead.
