Ron Paul said Saturday he would keep up his strategy of campaigning in states holding presidential caucuses after his second-place finish in Maine's contest.

Paul told CNN's Wolf Blitzer that the caucus strategy made sense for his campaign, which has struggled to raise the amounts of money posted by his competitors or the super PACs that support them. He said he would campaign in primary states only if they allocated delegates proportionally instead of winner take all and the cost of campaigning there didn't exceed his budget.

"We're going to continue like we are doing, the smaller states, the caucus states where we can accumulate delegates," Paul said. "We had a good day. We are convinced we will win the majority of the delegates out of Maine today."

While the state's GOP chairman announced Saturday that former Massachusetts Gov. Mitt Romney had won the Maine preference poll with 39% of the vote, the results there are non-binding, meaning delegates could still be awarded to other candidates.

Paul said the cost of campaigning in large states didn't make sense for his operation.

"To compete with someone with hundreds of millions of dollars is difficult," Paul said. "So for us to spend $25 million and the difficulty we have with raising money with the odds of not coming in first, that is not a wise choice of spending money."

Paul agreed the race for the White House is rapidly becoming Romney's to lost.

Think he is pretty much there," Romney said. "He does have the money and the organization. He just doesn't have the enthusiasm that I think we have able to get in our crowds, you know, really excited about what he believes in. I think that's his biggest problem. But I would say yes, he is out in front and people are picking away at him. He lost a few but he picked up a little steam today. You have to give him credit for that."

Paul said Romney's disposition made him more appealing than the other candidates in the race, but that his positions were far from his own.

"It just happens that because I've known Mitt a while longer he is friendlier, but I don't sympathize more with his positions," Paul said.
