In campaign news, Rick Santorum and Mitt Romney split a number of weekend caucuses. Santorum easily won in Kansas, while Romney won in Wyoming. Romney also won delegates in Guam, the Northern Mariana Islands and the U.S. Virgin Islands. On Tuesday, voters head to the polls in Alabama and Mississippi — the states are seen as must-wins for former House Speaker Newt Gingrich. On Sunday, Santorum urged Gingrich to step aside.

Rick Santorum: “The Speaker can stay in as long as he wants, but I think the better opportunity to make sure that we nominate a conservative is to give us an opportunity to go head-to-head with Governor Romney at some point, and hopefully that will occur sooner rather than later.”
