I watched their various speeches last night, the irony is that Trump was rather humble in accepting victory, a bit out of place for him. It is possible that he sees winning as a real possibility and now has to pay attention to the other 64% of Republican voters.
He might be looking at the possibility of actually winning and starting to realize what a s#!tstorm is waiting for the victor in 2017.
Obama is pretty obviously just trying to run the clock out on his time in office, and leaving the mess for the next person to clean up.
If I were a candidate in either party, I'd be seriously considering handing the primary victory to someone else and saying, "See ya' in 2020!"
