Well President elect Trump made no campaign promises at all. Which is what makes this thread so comical.
Trump identifies issues and does not make promises.
President elect Trump clearly stated that anything he said was a suggestion. More candidates should run their campaigns like the President to be. If you are a candidate you are running with imperfect information about a situation and to make promises such as "you can keep your doctor" when that is actually impossible are at best ill advised.
The ability of the president to accept new information and flexible in his positions is a highly desirable attribute.
This goes right back to the foolishness of the people who are failing to get up to speed on modern politics. The "Trump supporters take him seriously but not literally, and Clinton supporters take him literally and not seriously" couldn't be more true.
We elect a mindset and a general direction. Specifics need to have committees, panels and preparation. Not a sound byte.
You didn't
really expect to get free college for everyone did you?
