WASHINGTON (AP) - Rick Santorum has overwhelmingly won the Kansas Republican presidential caucuses.

GOP front-runner Mitt Romney did not campaign in Kansas. Rival Newt Gingrich cancelled a scheduled trip to the state late last week to concentrate on Tuesday's upcoming primaries in Alabama and Mississippi.

In the other caucuses being held Saturday, Romney is showing strength in Wyoming. Some counties in Wyoming caucused earlier in the week. So far, Romney has five of the 12 delegates at stake, Santorum has two, Paul has one and one remains uncommitted. Three more will be determined later Saturday.

Romney padded his lead in the overall GOP nomination delegate race Friday night when he won all nine delegates on the island of Guam and an equal number in the Northern Mariana Islands.
