Ron Paul supporters took control of the Maine Republican Convention and elected a majority slate supporting him to the GOP national convention.
The results gave the Texas congressman a late state victory.
In votes leading to the close of the two-day Maine GOP convention, Paul supporters were elected to 21 of 24 delegate spots from the state to the Republican national convention in Tampa, Fla., giving him a demonstrative win in the state.
Paul, the last challenger to Mitt Romney to remain in the contest, finished a close second behind Romney in Maine's GOP caucuses in February.
Those results were nonbinding, however, and not everyone had a chance to cast a ballot before the results were announced, as a snowstorm forced the cancellation of some caucuses, including one in a Paul stronghold.
Romney won the February election with 39 percent of the vote to Paul's 36 percent. Rick Santorum's 18 percent and Newt Gingrich's 6 percent.
Nevertheless, the caucuses merely selected the delegates to the state's party convention, and at that event, 21 of 24 voted to nominate Paul.
