GOP presidential hopeful Ron Paul did not rule out a third-party bid for the White House, but said he's not inclined to do so if he doesn't win the Republican nomination.

The Texas congressman, who is making his third run for the White House, made his comments Sunday on CNN's State of the Union program.

"I have no intention of doing it," Paul told CNN. "Nobody's particularly asked me to do it and they know what I'm doing and I have no plans whatsoever to do it."

Paul was the Libertarian Party's presidential nominee in 1988 and ran for the GOP nomination in 2008. The Texan, currently fifth in recent national polls, is running a different campaign than his previous ones.

That includes more TV ads in Iowa, New Hampshire and other early presidential states and more time on the ground meeting with voters in town hall meetings and other settings. He is third, behind Herman Cain and Mitt Romney, in the latest Iowa Poll.

Paull told CNN that a third-party race "would cause a little bit of a problem."
