Gingrich, Santorum, Paul in Minnesota Monday. No Romney.

Minnesota will be awash in Republican presidential candidates Monday, in advance of Tuesday's caucuses.

• Rick Santorum, who campaigned in the state last Monday and Sunday, will visit the veteran's memorial in Rochester, Minnesota at 9:00 a.m. and give a health care speech at Rochester's Kahler Grand Hotel at 10 a.m. before moving on to Colorado, which is also holding its presidential contest on Tuesday.
• Ron Paul, who was in Minnesota Saturday, will return Monday for a 4 p.m. St. Cloud rally at the River's Edge Convention Center and a 7 p.m. Minneapolis rally at the Minneapolis Convention Center.
• Newt Gingrich will hold an  rally at the Ramada hotel in Bloomington, starting at 7:30 p.m.

Mitt Romney had visited Minnesota last week and was expected to return on Monday but instead announced Monday events in Colorado, where polling shows him doing better.

Instead, former Gov. Tim Pawlenty and former Ambassador John Bolton will rally Romney supporters at 4:45 p.m. at Romney's Minnesota campaign office in Edina. (But on Tuesday night during the caucuses, Pawlenty will be speaking in Kansas.)
