After officially entering the presidential race on Thursday, ex-senator Fred Thompson is seen as the favorite Republican candidate ahead of Rudy Giuliani, according to odds published by Beted.com. Thompson said he will stop “another Clinton” to reach the White House, but it’s still a long way for him, because Clinton odds are way better than any of her opponents. Rudy Giuliani is still the favorite in the most of sportsbooks, but differences with Thompson are very small.
