Former GOP head: Nomination could go to convention

Former Republican Party chairman Haley Barbour says the fight for the GOP presidential nomination could go all the way to the convention.

The ex-governor of Mississippi says he doesn't think that's likely, but he notes in a CBS "This Morning" interview that none of the candidates has taken control of the race.

He says such a scenario would be "unusual" but that "whoever we nominate, Barack Obama is the great uniter of Republicans."

Barbour also says that "historically, these nomination contests don't start until February, so it's mighty early in the game." He says Republicans should focus on the "anemic" economy.
