Bernie Sanders is holding onto his lead in Wisconsin, which has its presidential primary on Tuesday, according to a new poll out Sunday. 

And he continues to spark enthusiasm, drawing 1,800 people to an event at a 1,200-capacity theater in Wausau Sunday morning, and hoping to attract almost 10 times that to a rally Sunday evening in Madison. 

Supporting the findings of other recent surveys, the CBS News Battleground Tracker poll shows Sanders with the support of 49 percent of likely Democratic voters in Wisconsin, compared to Hillary Clinton’s 47 percent. The poll of 1,501 registered voters was conducted March 29-April 1, with a margin of error of 3.7 percentage points. 

CBS News reports: “Wisconsin Democrats by a wide margin would like to see the next president follow more progressive policies than President Obama, and are more inclined to believe that trade takes away U.S. jobs, both sentiments that appear to be helping Sanders, even as he trails Clinton on the measure of being prepared to be president.”

As political correspondent James Hohmann noted at the Washington Post this week, “The state has a long tradition of embracing radical/revolutionary progressives like Bernie.” 

Furthermore, Hohmann wrote, “Sanders benefits from Scott Walker backlash.”
