Renege on what? the Republicans never intended to cut off their major source of income in the first place.Obamacare is their bread and butter. It is free money for the pols. I said from the beginning, if Trump is going to be effective in bringing back the Republic he is going to have to rule by fiat and decree because he will never get a Congress that wants any of that, Republican, Democrat or anything else. Trump can trim aggressively and shrink the footprint of government, perhaps a whole lot, but if he does not do the things Congress will NOT do i.e. abolish- not trim or rationalize- the Agencies, all of them over and above the original 4 Departments of the original Cabinet, then as soon as he is gone from the scene they will all come roaring back and their re-advent will be much more catastrophic for Americans than just letting them continue as they are. America in 20 years will a Bureaucratic Totalitarianism, no matter what else Trump does if he does not decree the Agencies out of existence and ban their staff from further government employment.
I have said that from the beginning, but the butthurt Cruzers don't get it. Only he can undo this Oligarchy, Congress never will.
