NASHUA, N.H. -- More than 400 supporters gathered Sunday to hear Republican candidate Ron Paul speak on his plans to limit governmental power.

Paul said his ideas clearly separate him from the other Republican candidates.

"They're talking about more government," he said. "We just need better management of government. We don't need to go in that direction."

Supporters said Paul's message resonates with them.

"I'd like my freedom back," supporter John Dean said. "Freedom with responsibility, and Ron Paul is the only candidate that has a clear message."

Paul reiterated his belief on ending the war in Iraq and took aim at Republican candidate John McCain.

"He thinks it's necessary, and we ought to stay in Iraq for a hundred years," Paul said. "I say, no way."

Paul said he is confident that New Hampshire will play a central role in his campaign.

"There's a lot of enthusiasm, a lot of people knocking on doors and making phone calls," he said. "I think our momentum is building."

The latest WMUR/CNN tracking poll shows Paul in fifth place with 10 percent support.
