According to a new Marquette University Law School Poll, Wisconsin Democratic U.S. Senate nominee Mandela Barnes is leading by seven points in his race against Republican U.S. Sen. Ron Johnson, the current incumbent.

The Milwaukee Journal Sentinel reports that Barnes garnered 51 percent support while Johnson, who is running for a third term, registered at 44 percent support in the poll.

The survey’s snapshot was the first update since the August primary as well-known incumbents attempt to fight off the challenges brought by lesser-known opponents.

In the governor’s race, Democratic Gov. Tony Evers is in a tight battle with GOP nominee Tim Michels, according to the poll. Evers leads Michels 45 percent to 43 percent, which is within the poll’s margin or error.

"It's clear that the two non-incumbent candidates (Barnes and Michels) still have a lot of voters that don't have impressions about them, so the campaign has every opportunity to make a big difference there," poll director Charles Franklin said, according to the Journal Sentinel.

The poll also reveals that Barnes is making a good impression as 50 percent of respondents said “he cares about people like you,” compared to just 41 percent who said the same about Johnson.

Barnes was viewed favorably by 37 percent and unfavorably by 22 percent with 41 percent not providing an opinion. This contrasts Johnson, who had a 38 percent favorable rate and a 47 percent unfavorable.
