There are still many Republicans who are privately very close to their Democrat cousins in ideology.
Remembering the recent campaign, if these so called "Republican Representatives" were honest, Obamacare would be over. But, honesty is a word which means very little to these swamp inhabitants.
Throughout the campaign and on, I've described it this way. Voters are really fed up, and much more informed than the arrogant SOBs who manipulate us realize. What voters did in November is give the DC slime a lot of rope, total control, no excuses. They could either use that rope to hang themselves or as a lifeline. They chose. All they had to do is pass again one of those over 50 bills they sent to Obama when they knew it would be vetoed.
The nation cannot be saved if those who got elected as Republicans continue to backstab the agenda on which they campaigned. President Trump is doing the correct thing saying "enough". Part of being a great negotiator is knowing when to walk away, and mean it.
