In Iowa, voters can change their registration even on the night of tomorrow's caucuses in order to caucus with Republicans. Some have switched already to vote for Dr. Paul. After he spoke to more than 700 people at the University of Northern Iowa in early December, Alison Gowans of WestDesMoinesPatch.com reported: "In a way, the atmosphere was reminiscent of the crowds of young voters who greeted Barack Obama when he campaigned four years ago. Some Paul supporters in the crowd, in fact, said they voted for Obama in 2008 — but wouldn't do so again. Instead, this time, they are all about Ron Paul." The Paul campaign registered 70 voters after the candidate's talk. Some were not happy to become Republicans, yet still did it so they could vote for Dr. Paul.
