Just looks like a realistic guy telling the plain honest truth to me. Yea, he might lose. What do you want him to do? Stick around like kasich and Cruz pretending he is going to win even after its a mathematic impossibility? In all likelihood a democrat was going to win no matter who runs. Same thing 4 years from now. If you didn't see that 4 years ago I don't know what to tell you. They have the votes.
With a decent candidate, The Rep's actually probably had a better chance at this election than they have had in a while. But they have pretty much completely torpedoed their chances (whether that was intentional or not is up for debate)
