Looking at Politico's calendar of daily events, the one thing that jumps out at you is that Rick Santorum apparently lives at random Iowa coffee shops, libraries etc.:
http://www.politico.com/2012-election/calendar/No one is matching his groundwork in Iowa it seems.
Now, I don't believe he'll win it, but could this let him do surprisingly well? Could he pull of 2nd and make everyone but the winner look real bad?
Imagine the headlines, ''
Cain wins Iowa Caucuses convincingly, Romney comes in after *sn* Santorum"
