Far from it. The fact that he's even won statewide office before proves that he has a lot of potential for the future. One loss won't end his entire career.
the guy only won statewide elections because they were races where the spotlight wasn't on him. With the spotlight on him, he chokes EVERY TIME. Conway's career is done like Disco.
He's moderate enough to beat any anti-Democrat streak. Obama dragged him down this year (and in 2010). Come 2017, when Obama is out of the White House, all bets are off.
He's lost every time.
Come on Oldies. He's lost to Matt Bevin and Rand Paul. Imagine how badly he'd be trounced by the McConnell machine. He's done.
