DES MOINES --- The revolution is "is alive and well and growing," especially in Iowa, where U.S. Rep. Ron Paul hopes to send a message.

The Iowa GOP Straw Poll in Ames Aug. 13 will be that platform for that message, the Texas congressman told 150 people Monday in Des Moines.

"We're in Iowa for a very precise reason," said Paul, who joked he visits so often just to meet everyone. "Iowa is a bellwether. It can send signals. That's what we're really looking for - a signal."

And the Ames straw poll will send a "very, very important message," he predicted. Paul's campaign just spent $31,000 to claim the top spot outside the Hilton Coliseum at Iowa State University where the straw poll will be held. Paul outbid rivals for the prime real estate.

Despite the enthusiasm of his supporters, Paul has his work cut out for him. He received the support of 7 percent of likely Iowa caucus-goers in a new Iowa Poll by the Des Moines Register.

The enthusiasm is growing, said Lexy Nuzum of Winterset, who heard about Paul four years ago but didn't become involved in his 2008 presidential bid. Now she's co-chairwoman of Paul's Madison County committee.

Like several others, Nuzum's chief concern is the U.S. involvement overseas.
