Minnesota Caucus 2012: Live Updates From The North Star State

Going into the 2012 Minnesota caucus on Tuesday, former U.S. Senator Rick Santorum is looking to score his first win of the primary election season.

HuffPost's Mark Blumenthal reports:

On Monday night, PPP released final data on new automated, recorded-voice surveys showing former Sen. Santorum (R-Pa.) leading in Minnesota and Missouri and running second to former Massachusetts Gov. Mitt Romney in Colorado.

PPP conducted surveys from Feb. 4 to Feb. 6 in the two caucus states, Colorado and Minnesota. In Colorado, a state where Romney carried 60 percent of the caucus vote four years ago, they give Romney a 10 percentage-point lead -- 37 percent to Santorum's 27 percent -- followed by Newt Gingrich at 21 percent and Ron Paul with 13 percent.

On Tuesday, candidates vying for the Republican presidential nomination will also compete in the Colorado caucus and a non-binding primary in Missouri.
