1. He was too qualified. Kasich did a half-way decent job as Governor of Ohio.
2. Kasich didn't go negative.
3. Kasich was too qualified and experienced for the CONS.
4. Kasich was actually a true Conservative.
5. Kasich was too presidential.
6. Kasich is not a racist.
7. Kasich treats women with respect.
8. Kasich was too honest.
9. Kasich wasn't scandal-ridden.
10 Kasich is sane.
All the traits that decent people think a president should have mean nothing to CONS. The CONS picked the worst of the worst when they picked Trump. Creepy Ted Cruz was a close second but Cruz is sane and that turned off a lot of CONS.
CONS reject true conservatism, civility, facts, intelligence, professionalism, job qualifications, and positivity while embracing bigotry, dishonesty, stupidity, ignorance, incompetence, hostility, and hate.
