MILWAUKEE – A new Marquette Law School Poll finds 44 percent of Wisconsin likely voters supporting Democratic candidate Hillary Clinton for president and 37 percent supporting Republican Donald Trump, with Libertarian Gary Johnson at 9 percent and Green Party candidate Jill Stein at 3 percent. Six percent do not express a preference, saying that they will vote for neither candidate, will not vote or don’t know how they will vote.

The poll was conducted Oct. 6-9 and was completed before the second presidential debate. The poll began interviewing voters the day before the Washington Post published a story and a 2005 recording in which Trump described, in graphic detail, his treatment of women.

“The publication appears to have caused a significant shift in Wisconsin voters’ attitudes, across several different demographics,” said Charles Franklin, director of the Marquette Law School Poll.

In the previous Marquette Law School Poll, conducted Sept. 15-18, Clinton was supported by 41 percent and Trump by 38 percent among likely voters, with Johnson at 11 percent, Stein at 2 percent and 7 percent not having a preference.

In the new poll’s head-to-head matchup (as opposed to the four-way race), Clinton receives 46 percent to Trump’s 42 percent of likely voters, with 9 not giving a preference. In the September head-to-head matchup, among likely voters, Clinton had the support of 44 percent and Trump was supported by 42 percent, with 12 percent not expressing a preference.

In Wisconsin’s U.S. Senate race, 46 percent of likely voters support Russ Feingold, 44 percent back Sen. Ron Johnson and 4 percent choose Libertarian candidate Phil Anderson. Five percent do not express a preference. In September, Feingold was supported by 44 percent, Johnson by 39 percent and Anderson by 7 percent, with 10 percent not giving a preference.

In a head-to-head matchup, among likely voters, 48 percent support Feingold and 46 percent support Johnson, with 6 percent lacking a preference. In September, Feingold was the choice of 47 percent to Johnson’s 41 percent, with 11 percent not stating a preference.

The full sample of the Oct. 6-9 survey comprises 1,000 registered voters interviewed by cell phone or landline, with a margin of error of +/- 3.7 percentage points. Results for likely voters are based on 878 respondents, with a margin of error of +/- 3.9 percentage points. When broken down by day of interview, the margin of error for Thursday‘s sample is +/-5.9 percentage points and +/-7.8 percentage points for the Friday and combined Saturday and Sunday samples.

Shifts following release of Trump 2005 video

The October poll began interviewing voters on Thursday, one day before the Washington Post report on the 2005 Trump video. Comparing voter responses by the day interviews took place allows an estimate of how vote preferences shifted after the release.

Among all likely voters interviewed on Thursday, Trump led Clinton by 1 percentage point. Among those interviewed on Friday, Clinton led Trump by 6 percentage points. On Saturday and Sunday combined, Clinton led Trump by 19 percentage points.

Shifts are also present across several demographic and political groups. Among men, Trump’s 12-point lead on Thursday expanded to a 16-point advantage Friday but reversed to a 1-point Clinton advantage Saturday and Sunday.

Among women, the shift was larger. A Thursday 9-point advantage for Clinton shifted to a 27‑point advantage on Friday and to a 33-point advantage on Saturday and Sunday.

Among evangelical or born-again Protestants, one of Trump’s stronger supporting groups, Thursday saw Trump leading Clinton by 40 percentage points. That advantage shrank to 23 percentage points on Friday and to 16 percentage points on Saturday and Sunday.

Non-Hispanic white voters without a college degree have been a strong supporting group for Trump. On Thursday, Trump held a 15-point advantage over Clinton with these voters. On Friday his advantage was 3 points, and on Saturday and Sunday this group of non-Hispanic whites without a degree favored Clinton by 7 points over Trump.

Among non-Hispanic whites with a college degree, Clinton led by 16 percentage points on Thursday, a margin that reversed to a 4-percentage-point Trump advantage on Friday before reversing again to a 26-percentage-point Clinton lead on Saturday and Sunday.

The few Democrats supporting Trump on Thursday, 7 percent, fell to 2 percent on Friday and rose to 3 percent on Saturday and Sunday, while party loyalty to Clinton rose from 88 percent on Thursday to 95 percent on Friday and settled back to 89 percent on Saturday and Sunday.

Republicans maintained substantial party loyalty for Trump over the four days, though not as high as Democrats showed for Clinton. On Thursday, Trump received 80 percent support from Republicans, which slipped to 70 percent on Friday before rising to 78 percent on Saturday and Sunday. Clinton received 5 percent of Republicans’ support on Thursday, 9 percent on Friday and 3 percent on Saturday and Sunday. Support for Libertarian Party candidate Gary Johnson rose from 8 percent of the Republican response on Thursday to 12 percent on Friday and 11 percent on Saturday and Sunday.
