Republicans did make the very sound point that, during the years Obamacare has been settling into place, health insurance costs for a great many people have shot up while insurance providers have abandoned less profitable markets. Mr. McCain, himself, said in a press conference on Thursday that there is only one health insurer in each of his state's counties. That is a serious problem, but it was not seriously addressed in any of the varied proposals offered as Obamacare replacements. The only GOP priority was to deliver on the party's longstanding promise to undo what President Barack Obama and the Democrats did in 2010. Other than a huge tax cut for the wealthy, though, they never firmed up the details of a workable replacement plan.
