We should remember that this is the logical outcome of Mitch McConnell repeatedly siding with liberal and moderate Republicans. It was Senator McConnell who sided with Lisa Murkowski after she left the GOP. McConnell aligned the NRSC against the Republican candidate against Murkowski. It was McConnell who turned the NRSC into an incumbent protection service that tried to even get Charlie Crist elected as a Republican.
Until leadership changes in the Senate GOP repeal will not be possible.
