There are plenty of Newt people in Missouri - I’m one of them, I’m going to see if I can caucus next month, and I’m no “casual voter”.
(What is that, by the way? You mean like those who elected Obummer because they thought he was running for American Idol?)
Casual voters, ie Newt is fine, Santorum is fine. Here in Southeast MO, people that have the desire to caucus are pretty fired up about Santorum now. Also, Santorum is the featured speaker here on Lincoln Day, which is a really big deal in our very conservative area. There have been Santorum fliers in the mail and Santorum billboard. Nothing from Gingrich, since he blew off the primary.
