Trump’s strongest areas are in the northern and western parts of the state in areas covered by the 3rd and 7th congressional districts, though Cruz only trailed by one point. Cruz also held a lead in the Green Bay media market and had a two-point lead over Trump among respondents without a college degree.

State Rep. James Edming, R-Glen Flora, the first state lawmaker to publicly back Trump, said he is confident Trump will win in his district, located in the northwest part of the state, far from the influence of Milwaukee area conservative talk radio, which battled with Trump this week.

“The more the news media and the press bashes him, the harder hit he’s going to make,” Edming said. “That just makes me ugly. If you can’t get out there to say what you want to say, don’t bash the other guy.”

Sanders has the largest lead in the Madison region, but he also has a slight advantage in the Milwaukee region. Clinton has performed better in states with large minority populations. Franklin said the results show “turnout on Tuesday could make interesting differences.”

Cruz and Sanders held events in Madison on Wednesday, while Trump held rallies in De Pere, Appleton and Green Bay after slamming Gov. Scott Walker at a rally in Janesville on Tuesday. Walker endorsed Cruz on Tuesday.
