The House cleared the way Friday for speedy action to repeal the Affordable Care Act, putting Congress on track to undo the most significant health care law in a half-century. With a near party-line vote of 227-198, the House overcame the opposition of Democrats and the anxieties of some Republicans to approve a budget blueprint that allows Republicans to end major provisions of President Barack Obama’s health care law without the threat of a Democratic filibuster in the Senate.
