With the Iowa caucuses three days away, I invited Josh Kraushaar (executive editor of National Journal’s Hotline) to join me on KTRS/St. Louis and analyze how things look on the weekend before the first votes of the 2012 presidential election season are cast. I asked him why the caucus matters, considering that Iowa Republicans chose Mike Huckabee 4 years ago and rarely are a predictor of who will win the nomination. We also discussed why Mitt Romney’s pressing so hard to win there, how much of a factor Ron Paul will be, and how much Newt Gingrich has faded from view. He also revealed an odd decision by the GOP in Virginia, where voters will have to sign a party loyalty oath before being allowed to vote in the primary.
