According to National Journal, Rep. Ron Paul of Texas will be running for president in 2012:
Rep. Ron Paul, R-Texas, whose outspoken libertarian views and folksy style made him a cult hero during two previous presidential campaigns, will announce on Tuesday that he's going to try a third time.
Sources close to Paul, who is in his 12th term in the House, said he will unveil an exploratory presidential committee, a key step in gearing up for a White House race. He will also unveil the campaign’s leadership team in Iowa, where the first votes of the presidential election will be cast in caucuses next year.
Paul, 75, ran as the Libertarian Party candidate in 1988, finishing with less than one half a percent of the vote. After more than a decade as a Republican congressman, Paul gave it another shot in the 2008 presidential election, gaining attention for being the only Republican candidate calling for the end to the war in Iraq and for his “money bomb” fundraising strategy, which brought in millions of dollars from online donors in single-day pushes.
