WKOW 27: Madison, WI Breaking News, Weather and SportsMinnesota could be a problem for Romney

ST. PAUL, MN (WKOW) – Mitt Romney might face a significant challenge in Minnesota.

Ever since the former Massachusetts governor won the state's caucuses in 2008, the state turned as contentious as any other state. 

Romney campaigned four years ago as the more conservative choice compared to Arizona Sen. John McCain.  But this time, Romney is the front-runner against more conservative rivals, Newt Gingrich and Rick Santorum.

This makes Tuesday's caucuses unpredictable.
