UNDATED (WSAU) With all the recall fever in Wisconsin, the state’s voters have hardly had time to focus on the April third presidential primary. But that will change today, when Ann Romney visits Middleton and Milwaukee. The wife of Republican candidate Mitt Romney will appear at a diner in each city. Romney’s main challenger, Rick Santorum, is due in Saturday for a conference in Milwaukee put on by the Americans for Prosperity.

Recent polls show Santorum leading in Wisconsin. But Wisconsin G-O-P strategist Mark Graul – who’s not involved with either campaign – says Romney still has the edge. Graul said the former Massachusetts governor had a major head start in setting up his Wisconsin organization. It’s been forming since January, with leaders in every major county. State Senate Republican Alberta Darling of River Hills and former state Senator Ted Kanavas of Brookfield head the state’s Romney organization. Nick Lauren is the state director for Santorum’s campaign – and he believes his man has the best grass-roots operation in Wisconsin with chairs in all 72 counties.
