Mitt Romney won the presidential preference voting context by Maine Republicans in the party's municipal caucuses, which were heavily attended across the state. Romney, the former Massachusetts governor, had a little over half of the vote with about two-thirds of the towns holding caucuses reporting Saturday. John McCain worked to keep his vote above 20 percent, trailed by Ron Paul and Mike Huckabee. The nonbinding votes, the first step toward electing 18 Maine delegates to the Republican National Convention, were taking place in schools, fire stations and town halls across the state. Despite a sleet storm the night before that left much of the state coated with slush and ice Saturday morning, cars jammed the parking lot outside an Augusta elementary school where Kennebec County municipalities were caucusing.
