I wouldn't count on the repeal being dead just yet, the house version also looked dead for a while, but then it came back and passed the 2nd time around.
However, this does leave the Republicans in a lot of trouble. They've had 6 months to work on this already, and they have no healthcare bill, no budget, no tax reform and no increase in the debt ceiling, so the next couple of months could get really ugly for them. And it only gets harder next year, as they approach the midterms and the possibility of a Democratic house.
