Barack Obama defeated Hillary Rodham Clinton in Maine presidential caucuses, grabbing a majority of delegates as the state's Democrats overlooked the snowy weather and turned out in heavy numbers for municipal gatherings. Democrats in 420 Maine towns and cities were deciding Sunday how the state's 24 delegates will be allotted at the party's national convention in August. Despite the weather, turnout was "incredible," party executive director Arden Manning said. With 70 percent of the participating precincts reporting, Obama had 57 percent of the vote, while Clinton had 42 percent. The voting came a day after Obama and Clinton made personal appeals here, and after Obama picked up wins in Louisiana, Nebraska, Washington state and the US Virgin Islands.
