We always knew there was gonna be a 1~2 year off-ramp, to lessen political damage to the GOP in 2018, but like Ryan's House before (HFC signed off just to get it out of their hair, imho) the Senate is also unable to pass a clean repeal.
I believe it's got just as much to do with Reince and this Administrations bungling, the Lobbyist are the icing on the cake.
Both have proved deadly to an already nearly impossible scenario.
