Republicans will not vote for another scum-sucking Beshear.
It depends. I know a lot of people that loved Trump and Bevin. As long as they were hurting other people, that was fine with their sheep followers. But when it hits home, and impacts them personally they suddenly have their eyes opened and view things differently. "Hurt the Mexicans? Cool. Hurt the African Americans? Fine by me. Hurt the Muslims? Woo hoo! Attack the LGBTQ community? Awesome! Hurt teachers? YOU SONOFABITCH, MY DAUGHTER IS A TEACHER HOW DARE YOU!!!"
I know several "Republican" Trump bootlickers that absolutely hate Bevin and will be voting against him strictly due to the education/teacher stuff.
Bevin won because of apathy/low voter turnout. There is a pretty concerted effort to vote him out, and a lot of people that voted for him will not be doing so this time around. Plus, Bevin is awful. Pushes unconstitutional/illegal reforms. Ignores the laws. Acts like a jerk towards Kentuckians, the courts, and the press. Has a lot of shady dealings (his buddy the IT guy, the sweet deal on his new home, the Braidy Industries scam). Corruption is corruption, no matter the party.
