Republican Rep. Ron Paul said front-runner Mitt Romney's inability to brush back challenges in votes Tuesday "opens up the door" to him and others looking to deny the former Massachusetts governor the party's presidential nomination.
Paul, who represents the 14th Congressional District of Texas, was headed for a solid second-place in Minnesota's caucuses, which were won by former Pennsylvania Sen. Rick Santorum. Santorum also won Missouri and was in the hunt for a victory in Colorado's caucuses.
Paul was on course to capture more than a quarter of Minnesota's vote. He was a distant third in Missouri's non-binding primary and far back in Colorado.
The congressman said of the night's results: "I think it splits the vote and sort of opens up the door to us."
At a campaign rally in Minnesota on Tuesday, Paul said he was pleased with his showing in recent caucus contests.
He said he will continue to compete and collect delegates to the Republican convention, saying it is the best way to promote his campaign's message.
Without naming his fellow Republican candidates by name, Paul said he is the only candidate who will offer real cuts to the federal budget and is the true conservative in the race.
Romney won Minnesota convincingly in his 2008 bid for the GOP nomination. He didn't put much personal effort into the state this time, but he visited once and loaded up on campaign mailings to GOP activists.
In Paul's case, he invested plenty of time and money in Minnesota as he searched for the first win of his campaign. He said he's happy with the results and will shift his sights to Maine, where caucus results are due Saturday.
None of Minnesota's 40 eventual convention delegates were bound by preference ballot results. Paul's advisers said their supporters focused on flooding local party slates; it could give them power to influence the selection of Minnesota's national delegates in May.
"The straw vote is one thing and there's another thing called delegates," Paul told a roaring crowd at his Golden Valley party. "That is where we excelled."
In a brief appearance at Coon Rapids Middle School, Paul waded through a crowd to sign autographs, pose for photos and remind people to vote. He declined to make any predictions on the Minnesota outcome before heading to another suburban Minneapolis caucus site.
Paul said his candidacy was perfectly built for Minnesota. "They love liberty, they don't like wars and they certainly don't like the Federal Reserve," he said.
One caucus-goer in Coon Rapids, truck driver Rod Garberson, said if Paul isn't the fall nominee the Republican Party won't get his vote.
"I gotta tell ya, this time I'm pretty well stuck on not supporting the party even if it means eight years of Obama and we all stand in bread lines for five hours for a sack of potatoes," Garberson said.
Paul finished fourth in Minnesota four years ago with 16 percent.
