Ron Paul may be considered a “fringe” conservative for his beliefs, but as a U.S. congressman running for a major party presidential ticket he received some bizarre coverage on CNN Friday. Anchor Carol Costello chuckled as the network played a clip of comedian Conan O'Brien mocking Paul's presidential bid, before asking her panel about the 2012 presidential field. “We couldn't help but play a Conan O'Brien spot to lead into this Ron Paul segment,” Costello admitted with a grin during the 10 a.m. EDT news hour Friday. The clip featured TBS's O'Brien laughing at Paul's lax positions on the legalization of heroin and prostitution. “Yeah, his campaign slogan is 'Let's just see what would happen,'” O'Brien joked.
