rick santorum people see him and some of the comments she heard last night rick santorum seems to be most like us. he might be a catholic, we are evangelical. he connects with us and he seems authentic and he seems very serious. yet very approachable at the same time. this is with 40% undecided as brit said, it's imperil columbus to predict. i would have to say romney. >> bill: i wonder how many of the caucus voters are interested who could beat president obama. that becomes mitt romney's primary motivator. it isn't mitt romney the idealogue because he isn't one. is he a businessman/politician. rick santorum is an ideological guy. i'm not saying that as a pejorative. is he a conservative with conservative views. i'm wondering if this year the economic circumstance is so horrendous that the iowa caucus voters will say you know what? i'm going to support the guy ohio think most will likely to beat the president.
