Iowa disproved your ‘analysis’ that people haven’t sat up and noticed Santorum.
This analysis, a month ago - totally valid. But things change.
FYI, people did not sit up and take notice of Santorum in IA. They listened to their preachers. As happened in ‘08, there was a last minute push by IA’s Evangelical leaders. Apparently Evangelical voters do what their preachers tell them. There are not enough Evangelicals to get Santorum elected, as there were not enough Evangelicals to elect Huckabee.
