The Iowa Caucus is finally in the books, and hundreds of reporters are saying adios to the heartland. I said my own goodbye to Iowa a little more than a year ago, when I packed up my old Cadillac and drove the 1,864 miles to San Jose. Looking at the results from Tuesday night, when Mitt Romney edged out Rick Santorum by a mere eight votes and Ron Paul made his presence felt, I’m left thinking two things: One, no one benefited more than Romney from the suspension of Cain’s campaign, which dispersed those tea party voters; and two, Santorum’s support will likely fade the further he gets from Iowa.
