Ryan is just the front man for the current establishment effort to weaken Trump. Romney is playing bad cop and rehashing the tax return angle.
The overall ineptitude on display is breathtaking. Trump is in the drivers seat and they are sitting in the back seat with their Playskool steering wheel thinking that they are actually driving the car.
They are fighting. This is the first time the party has been threatened, and there is no way to prevent it, or prepare for it, because it is a political movement. I don't blame the party players for claiming "all is well" as their ship sinks. They are likely happy that the press is as inept as they are, and is accepting the line that unification is proceeding.
Wait for Trump to bring into view that "unification" in an election contest is unification behind a candidate, not unification behind some principles. So, how is unification behind the candidate going?
