WASHINGTON (AP) -- Mitt Romney has won the Republican presidential delegate vote at Wyoming's county conventions. That adds to his advantage in the party's race for the nomination.
Earlier Saturday, Rick Santorum won the GOP caucuses in Kansas.
In Wyoming, Romney won six delegates. Santorum gained three and Ron Paul one. Another remains uncommitted, and one more is still to be decided.
Earlier Saturday, Romney further padded his delegate lead by winning all nine delegates on the island of Guam and nine delegates in the Northern Mariana Islands.
Tuesday's upcoming primaries in Alabama and Mississippi now loom as critical. Polls show a close race in both states, particularly Alabama.
