MILWAUKEE — A new Marquette Law School Poll finds Democratic candidate Hillary Clinton with support from 46 percent of Wisconsin registered voters and Republican candidate Donald Trump with support from 36 percent in a head-to-head presidential matchup. Sixteen percent say they will vote for neither candidate, will not vote, or don’t know how they will vote.

In the most recent Marquette Law School Poll, in July, Clinton had 43 percent support and Trump 37 percent, with 18 percent saying they would vote for neither, would not vote or didn’t know.

Among likely voters, i.e., those who say they are certain they will vote in November, Clinton is supported by 52 percent and Trump by 37 percent in the new poll, with 10 percent saying they will support neither candidate. In July, likely voters gave Clinton 45 percent support, Trump 41 percent and 14 percent said they would vote for neither.

In a four-way matchup including Clinton, Trump, Libertarian candidate Gary Johnson and Green Party candidate Jill Stein, Clinton is supported by 42 percent of registered voters, with Trump at 33 percent, Johnson at 10 and Stein at 4. A total of 11 percent in that matchup say they will vote for none of the candidates, won’t vote or don’t know how they will vote. Among likely voters, Clinton receives 47 percent, Trump 34, Johnson 9 and Stein 3. In July’s four-candidate question among registered voters, Clinton received 40 percent, Trump 33, Johnson 10 and Stein 4.
