Mitt Romney won the Wyoming Republican presidential county caucuses, news sources report, and he also won GOP Presidential caucuses in the U.S. Virgin Islands, Guam and the Northern Mariana Islands.

In Kansas, Rick Santorum handily won the GOP presidential caucuses in the run-up to Tuesday's primaries in Mississippi and Alabama, the Associated Press reported. Santorum won 51 percent of the vote, gaining 33 delegates. Mitt Romney won 21 percent of the vote, Newt Gingrich followed with 14 percent, and Rep. Ron Paul made a fourth-place showing with almost 13 percent of the vote.

In two American islands located in the western Pacific Ocean region, the Wall Street Journal reported that Romney won all 18 combined delegates in the U.S. territories of Guam and the Northern Mariana Islands.

Elsewhere, the Associated Press reported that Romney won seven delegates in the U.S. Virgin Islands, another American territory. Ron Paul received one delegate from the islands, and one delegate remains uncommitted.

Back in Wyoming, with 100 percent of the state's precincts tallied on Saturday evening, Politico reported that Romney won the state's caucuses with 44.1 percent of the vote and seven delegates. Rick Santorum came in second place with 27.5 percent of the vote, earning two delegates and one disputed delegate. Ron Paul finished in third place, with 12.2 percent of the vote and one delegate, and Newt Gingrich came in last, with 0.5 percent of the vote and no delegates. One undeclared delegate remained out of the 14 delegates up for grabs over the course of the state's four-day county primaries. 

An additional fourteen at-large delegates will be chosen in April at Wyoming's state GOP convention, according to Politico. Party rules will award even more delegates to the state at the GOP national convention this summer as a reward for its solidly-Republican voting history, bringing the state total to 29 delegates, the same number allotted to Arizona, giving greater nominating influence to Wyoming than its relatively small population suggests.

To attain the party's presidential nomination, a candidate needs to win 1,144 total delegates at the national GOP convention in August. As of Saturday night, Romney had 454 delegates, the AP reports, a sum greater than that of all of his competitors combined.
