CNN's Wolf Blitzer: Sarah Palin and Marco Rubio Will Appear Together

Until now he's kept his distance from celebrity conservative Sarah Palin, but Marco Rubio, the Republican candidate who leads in the U.S. Senate race by a country mile, apparently sees a benefit in joining the sometimes popular, sometimes controversial former Alaska governor on a tea party stage.

Wolf Blitzer, host of "Situation Room," told his CNN audience Monday evening that, double-digit lead or not, Rubio still sees independent Charlie Crist over his shoulder.

But Blitzer's guest David Frum -- a conservative author and editor of www.FrumForum.com -- put a Palin-Rubio appearance in perspective. "Look, this is Marco Rubio's race to lose. He's that far ahead. But there's a huge flood of Democrat money still out there, and his campaign team knows he's in the Democrats' gun sites. ... They're saying, if (going onstage with Sarah Palin) is what it takes to put him over the line, let's do it."
