Geography of Nomination Race

Rick Santorum’s victory in the Kansas caucuses on Saturday wasn’t much of a surprise, but his margin was toward the high end of expectations as he took 51 percent of the vote to Mitt Romney’s 21 percent. It was the largest margin of defeat for Mr. Romney in caucus or primary to date, although he lost the “beauty contest” primary in neighboring Missouri by almost as large a margin.
