But before we go there, I also want to note that today is Iowa, and so we're about to turn a big corner in what is fast becoming one of the wackiest years in American political history. I'm going to sit down tonight after the caucus results come in and write to you again, for aspecial edition of Thoughts from the Frontline that will hit your inbox tomorrow. Along with Iowa, I want to delve into the issue of what a "brokered convention" would mean for the Republican Party, and what one would look like.
