A new NBC News/Marist poll suggests that GOP candidate Mitt Romney will win the Wisconsin primary comfortably on Tuesday, as numbers show him with 40 percent of the support of likely Republican voters, while rival Rick Santorum sits at 33 percent. But President Obama, who carried Wisconsin by 14 points in 2008, will likely beat every GOP candidate if the election was today. Against Santorum, Obama leads 51 to 38 percent. Against Romney, Obama leads 52 to 35 percent.
