AUGUSTA, Maine (AP) — Maine Republicans have handed Texas Congressman Ron Paul a late state victory.Paul supporters wrested control of the state party convention and elected 15 at-large delegates from Maine to the GOP nominating convention in Tampa, Fla. The other delegation seats remained undecided. Maine is allotted a total of 24 delegates to the national convention.The libertarian-leaning congressman is the last challenger to remain in the contest for the Republican nomination. Saturday's turn of events in a neighboring state to where Romney served as governor would indicate the GOP has not yet united behind the presumptive nominee, and there are indications the infighting may last all the way to the national convention.With 36 percent of the vote, Paul finished a close second behind Romney's 39 percent in February's GOP caucuses.
