Remember when conservative pundit Pat Buchanan ran for the GOP nomination in 1992, miffed with former President George H.W. Bush's policies? Now there's talk of another media big shot considering a bid: CNN's Lou Dobbs. Fans say he'd most likely run as a third-party populist, as Ross Perot did the same year Buchanan ran. A TV business anchor, Dobbs has morphed into a powerful voice calling for new national leadership and ending illegal immigration. While not ruling out a run, he says, "I've got a day job that I love." Dobbs, however, says that he is desperate for a change in the direction of the country. Asked about accepting a vice presidential nomination, he says, "How about secretary of state? I don't want to seem overly ambitious."
