Winner of the week: Mitt Romney. Poised to become the first Republican in modern history to win both the Iowa caucuses and New Hampshire primary, Romney already is airing television ads in Florida and is positioned to wrap up the nomination in the Sunshine State. His rivals barely nicked him in back-to-bag debates this weekend.

Loser of the week: Connie Mack. He's the overwhelming frontrunner to win the Republican U.S. Senate nomination, but on a critical measure he looks strikingly underwhelming: money. His campaign announced last week that he would report raising at least $500,000 in his first fundraising quarter. That's hardly a daunting show of strength.
