The Week That Was: Romney's up-and-down week


For Mitt Romney, it was a week of highs (his victory in Florida and expected triumph in Nevada) and lows ("I am not concerned about the very poor," Trump endorsement).

Mark Murray and Domenico Montanaro look back at the busy week leading up to the Nevada caucus. Romney wins Florida, has a slip of the tongue, and then Donald Trump endorses him.
