Right you are Bobert. If there had been a knock out candidate on the R side Huckabee would not have won. He appeals to a certain segment that is influential in politics here. Iowa is not full of rabid evangelicals but they are organized which played well for him in a caucus setting. A caucus is different than a primary, you don't just show up and pull a lever or fill in a bubble and then leave. I was at the caucus for about an hour and a half.
