The only thing surprising about this is that anyone who pretends to anything about politics is surprised.
I think what's really shocking is the degree of betrayal and the whole I-couldn't-care-less-about-the-optics attitude towards the base that got him elected.
Why is this surprising? He's a machine politician who has repeatedly demonstrated himself before and after the election to be a myth, a fraud, a charlaton who only has gotten ahead for his potential, not his deeds. I, and many other conservatives, could have told you that two years ago.
