Libertarian GOP Rep. Ron Paul over the weekend refused to rule out another presidential run in 2012, saying he would decide based on conditions next year.

Paul, who launched a long-shot campaign for president in 2008, reiterated that he has not made a decision whether or not to the enter the GOP field that is already crowded with potential contenders.

"I don't know. I get asked that question a lot and I think about it a lot. I haven't ruled it out but I'm far from ruling it in too," he told Fox Business Network. "I think it just depends on what's going on next year and I may do it, I may not." 

Paul withdrew from the GOP presidential primary in June 2008 after failing to win any states, but he attracted support from some young conservative and libertarian activists and won second place in 10 states. 

In February 2010, Paul won a straw poll of potential GOP presidential candidates at the Conservative Political Action Conference.

Paul and his son Rand — who won the GOP nomination for Kentucky's open Senate seat — both enjoy support from Tea Party groups for their focus on limiting the size of government.
