“His problem is that he picked one too many fights with the public sector unions who then spent a buttload of money to defeat him.”
This is what I think as well. Bevin was so on the right track but then he angered ,in particular, the Teacher’s Union in KY. Living as I do in a very heavily unionized state, New York, I am familiar with the union tactics and their incessant lobbying. They will stop at nothing to push their agenda.
He is also a jerk. Other GOP candidates won in the northern suburbs.
