I've got to think that Beshear's victory will embolden Jones; it shows that the right Democrat can beat an unpopular Republican in a statewide race. And, I'm sure he believes that Amy McGrath is not the right Democrat.
Bevin was probably the worst, most unlikeable, jerk of an incumbent this state has ever seen, despised by both parties. AND HE DAMN NEAR WON. Jones would be served well to pay attention to how badly all of the down-ticket races turned out. On top of that, Kentuckians don't mind putting a democrat in the governor's mansion, but sending a democrat to DC to mingle with Schumer, Sanders, Harris, Nancy, etc.? Totally different ballgame.
And Jones needs to stop playing the victim card. By talking about running, he's a candidate whether he's filed or not. Those rules are in play.
