Trail Mix: Arizona or Michigan - which state is a bigger win for Mitt Romney? Former Massachusetts governor Mitt Romney (R) had a better-than-expected night on Tuesday, sweeping the Arizona GOP primary and besting former senator Rick Santorum (R-Pa.) in Michigan - despite Santorum's eleventh-hour bid to woo Democratic voters in the Wolverine State. So, which state was the bigger win for Romney? Hint: As Ron Paul once put it, "There's one other thing called delegates, yeaahhh!" And how will Santorum's bid for Democratic votes play out as the campaign heads toward Super Tuesday? We take a look in the first edition of our new daily campaign video, Trail Mix: And yes, if there's one thing we're fans of here at the Election 2012 blog, it's creative names.
