He's scheduled to visit the Androscoggin County Republican Caucus at Geiger Elementary School at 10 a.m.
Paul also plans stops at 8 a.m. in Sanford and 12:30 p.m. in New Gloucester at the Memorial School gym in addition to a "Caucus Night Party" in Portland at 6.
"I think it's just the final strategy in Maine to hold our delegates firm in their support of Ron Paul," said state campaign chairman Paul Madore. "In all of this, this is really intended for those who have it in their heart to caucus."
Madore estimated that the congressman from Texas drew almost 800 people when he held a town hall meeting at the Ramada Inn on Jan. 27.
Most towns began caucusing Feb. 4. Maine's Republican Party leadership plans to make a night of the tabulated results Saturday with an event at the Portland Regency. It begins at 6:15 p.m. with a string of speakers, including U.S. Sen. Susan Collins. State Party Chairman Charlie Webster will announce the caucus winner at 6:45 p.m.
