Type of election: Caucus
How it works: 37 delegates will be at stake in the caucus. 25 are allotted statewide proportionately and the other 12 are awarded winner-take-all by congressional district. The caucus is closed.
Official election results: Kansas Secretary of State
Republican candidates: Newt Gingrich, Ron Paul, Mitt Romney and Rick Santorum (all others have dropped out or are polling at less than 1 percent)
Democratic candidates: There is no Democratic caucus.
Previous performance: In 2008, Romney finished fourth with just over 3 percent of votes. Paul finished third with more than 11 percent. Barack Obama won the Democratic caucus with 75 percent of the vote.
Television stations: Full list
Latest polling: It appears that no polls have been taken in Kansas.
Bottom line: Neither Gingrich nor Romney is seriously contesting Kansas, so it should be an easy win for Santorum. Paul should have a legit chance at finishing second.
Territories: Guam, U.S. Virgin Islands, North Mariana Islands
Type of election: Caucuses
How it works: Each territory will have a non-binding caucus and each territory has a total of six delegates and three Republican National Committee members who are delegates.
Bottom line: You'll be hard-pressed to find the results of these contests and with none of the candidates participating in them and the small delegate totals, they aren't going to have any real influence on what happens.
