WASHINGTON (AP) -- Mitt Romney is adding to his lead in the race for convention delegates with his win in Washington state's Republican presidential caucuses.
Romney has won at least 12 delegates while Rick Santorum and Ron Paul have each won at least three. Twenty-two delegates were still left to be awarded.
In the overall race for delegates, Romney leads with 185, Santorum has 90, Paul has 23 and Newt Gingrich has 33. It takes 1,144 delegates to win the nomination.
Washington Republicans use a multi-step process to award delegates, and Saturday's caucuses were just the first step. The Associated Press projects the number of delegates each candidate would win if there are no changes in their support throughout the process, which culminates in the party's state convention at the end of May.
