Bevin is probably done for, but I think Edelen and Beshear are the strongest. Conway definitely is not.
Almost everyone on this site (inculding myself) thought Conway was going to win. Election day comes, and Bevin not only wins, but he wins by so much that he dragged in the Republican Auditor candidate and nearly dragged in the Republican Attorney General and SOS candidates. It's very hard to see 2019 going well for KY Democrats. It's not as if the state is changing in a D direction demographically.
