<p>Two potential candidates for the Republican presidential nomination have been described as “frontrunners”: former governors Mitt Romney and Sarah Palin. According to pollster Scott Rasmussen, they’re the candidates with the most supporters among likely Republican-primary voters: Romney has 24 percent, Palin 19 percent. Intrade, the prediction market, has them as the most likely nominees: Romney is given a 23 percent chance of winning, Palin 15 percent. Each of them has a claim to being “next in line”: Romney because he was arguably John McCain’s strongest rival for the nomination in 2008, Palin because she was his running mate.</p>
