Obama and McCain 'to win Vermont' McCain wins Republican nomination
(about 1 hour later)
Democratic front-runner Barack Obama is projected to win Vermont, the first state to complete polling on a key day in the battle to run for US president. John McCain has won the Republican party's nomination to run for president in November with projected poll wins in Ohio, Vermont, Rhode Island and Texas.
But US networks say the contest between him and rival Hillary Clinton in the larger Ohio poll is too close to call. His closest rival, Mike Huckabee, has dropped out of the race and pledged to support Mr McCain's candidacy.
Republican John McCain - well ahead in his party's race - is projected to win both Vermont and Ohio. Democratic front-runner Barack Obama is projected to win his party's primary election in Vermont.
Voting to select party candidates has also been taking place in Texas and tiny Rhode Island. But rival Hillary Clinton is expected to take Rhode Island, ending Mr Obama's long winning streak.
