WASHINGTON (AP) - With support from a lone Republican, a key Senate committee Tuesday approved a middle-of-the-road health care plan that moves President Barack Obama's goal of wider and affordable coverage a giant step closer to becoming law. Maine Republican Olympia Snowe said she was laying aside misgivings for now and voting to advance the bill, a sweeping $829-billon, 10-year health care remake that would help most Americans get coverage without creating a new government insurance plan. "When history calls, history calls," said Snowe.
