But then, the Mexico wall was THE joke of an entire season of Arrested Development.

Sometimes it seems like Trump is playing Colbert, pretending to be a hypocritical moronic jackass completely lacking in self awareness just to expose how absurd Republicans can really be.

The idea that Republicans just follow along and support whatever he does, no matter the hypocrisy or absurdity, was exactly what Colbert was attempting to expose.

What is funny is that many Republicans believed Colbert at first, thinking he was on their side.

Trump could be playing this role in an attempt to crush the GOP for decades.He wanted to expose them as fools and tools that should not be allowed to govern.(Obamacare replacement LOL)

It that was his plan, he is doing a really good job, because that is exactly what is happening.
