Democrat David Crowley has edged his lead over GOP nominee Tom Tiffany in Wisconsin's governor race, according to a Marquette University Law School poll released Wednesday.
The survey indicates Crowley's backing among likely voters rose by 2 points from last month to reach 51 percent in October, while his 7-point margin over Tiffany sits within the poll's margin of error.
In the same poll, 44 percent of likely voters favored the former Republican U.S. House member, compared with 46 percent support for Tiffany in September, and 4 percent remain undecided ahead of the Tuesday midterm election.
Favorability for the Democrat climbed six points since the previous month, with the Republican's favorability increasing by one point.
Both candidates improved among independent voters; Crowley's share grew from 44 percent in September to 56 percent in October, while Tiffany's rose from 18 percent to 26 percent.
Crowley and Tiffany are contesting the seat of retiring Gov. Tony Evers (D) in the Nov. 3 election, where recent polls have shown the Democrat with a narrow advantage.
The Marquette poll also revealed higher enthusiasm among Democratic voters, mirroring a national enthusiasm gap. Eighty-two percent of Democratic respondents said they were "very" or "somewhat" enthusiastic about voting, versus 74 percent of Republicans.
The poll was fielded from Oct. 14 to 22 among 818 Wisconsin registered voters, with a margin of error of about 4.3 percentage points. Among the 668 likely voters, the margin of error was roughly 4.7 percentage points.
