Why did the Des Moines Register endorse Romney? The newspaper's editor explains

The Des Moines Register, the largest newspaper in Iowa, backed Mitt Romney late Saturday in his bid for the Republican presidential nomination.

The much-anticipated endorsement gives the former Massachusetts governor special bragging rights just over two weeks before Iowa's critical presidential caucuses on January third.

Citing the candidate's "sobriety, wisdom and judgment," the editorial board said that Romney was the most qualified candidate competing in the caucuses.

Today on American Morning, Rick Green, editor of the Des Moines Register, explains to Ali Velshi why his paper chose to back Romney.
