Why Trump’s Obamacare Promise Will Be So Hard to Keep

By Margot Sanger-Katz

As a candidate back in July 2015, Donald J. Trump promised that he would repeal Obamacare and replace it with “something terrific.”

The Senate voted, 51 to 48, on Thursday morning for a measure setting Congress on the path toward repealing President Obama’s health care law, and Mr. Trump is now a few days from taking office. The public, however, knows little more about his proposal than it did in 2015.
