(CNN) -- Ron Paul, the only candidate in the GOP race without a primary or caucus win, said Tuesday he was confident his campaign could move forward even if he doesn't place first in any of Tuesday's contests.

"Well we're gonna win some delegates, whether we come in one or two or three, I don't know exactly that," Paul said on CNN's "John King USA."

"But we feel positive about moving along and picking up more delegates. We'll have to wait and see."

Paul stressed his strength in the upcoming Maine caucuses, saying he was determined to continue his campaign by picking up delegates in caucus states.

"We're optimistic we're going to keep picking up delegates," Paul said. "That's what the other candidates are doing. Nobody else is about to at this point jump ahead of Romney. But we think we're going to keep doing. We have a very good chance on what's happening up in Maine."

Weighing in on the escalating violence in Syria, Paul said as president he would not advocate any American action in the troubled country unless Congress officially declared war.

"Well, that problem has been going on for many, many years, if not centuries," Paul said. "Bad governments. Look at what they did to communists. Killed hundreds of millions of people. So it's a tragedy, it happens in Africa all the time. But I'm not representing those countries as a congressman and as a president. I represent the United States. And I don't think it's a wise thing to get involved in the civil war that's going on in Syria."

Paul said tensions in Syria were tragic, but that hot spots would always pop up around the globe and the United States would never be able to patrol them all.

"I think it's none of our business," Paul said. "I think it's a tragedy, but I can point out many tragedies, many folds greater than this, but it's not in American interests."
