By Steve Holland MANCHESTER, N.H. (Reuters) – Republican presidential candidate Jeb Bush on Tuesday will lay out proposals to repeal President Barack Obama’s healthcare law and replace it with a system that provides a tax credit for the purchase of health plans and shifts power to the states. Bush will detail his plan at the New Hampshire Institute of Politics in Manchester to start a three-day campaign swing through the state, which holds the first-in-the-nation primary election on Feb. 9 on the road to the November 2016 election. “ObamaCare, a government takeover of more than one-sixth of the American economy, epitomizes why Americans are fed up with Washington. Jeb believes we must repeal Obamacare and offer a conservative vision and plan of health care for the future,” said Bush spokeswoman Allie Brandenburger.
