This isn't news to me. Republicans have failed to keep any of their promises since at least 2010. First, it was "give us the House and we will do this." So voters gave them the House and then they said "we need the senate to really get things done." So voters gave them the senate. Then it was 'give us the presidency so we can really do things." So now Republicans have both houses of congress and the presidency and still, the promises have not been kept.
I can only conclude that Republicans really don't want to end Obamacare, don't want to stop the invasion of illegals and "refugees." don't want to really fix our tax system, or do anythingn else they promised to do. They just want to collect the salaries, perks and benefits.
I was taught that our elected representatives are our employeees -- they work for us; we don't work for them. Well, I don't know of any employer who would put up with an employee who doesn't do the job -- at least not for long. Why do we, the voters -- the employers -- allow these employees to collect a check without doing their job?
Republicans have no intention of repealing Obamacare and, mark my words, they will be ok with some sport of Medicare for all scheme. Both parties crave power and what better power to have than the power over the life and death of their subjects?
