evidence: Trump’s repeated declarations over the past several weeks that he intends to finally repeal the ACA if reelected surprised many Republicans. Few GOP leaders have talked about uprooting the law since the party’s last effort failed, during Trump’s first year as president. At that point, Republicans controlled both chambers of Congress. But whereas the House, with Trump’s enthusiastic support, narrowly voted to rescind the law, the Senate narrowly rejected repeal. Three GOP senators blocked the repeal effort by voting no—including the late Senator John McCain, who dramatically doomed the proposal by signaling thumbs-down on the Senate floor. (Trump mocked McCain while calling the ACA "a catastrophe" as he campaigned in Iowa last weekend.)
