Trump can give Christie everything that the larger-than-life governor thinks he is entitled to: luxurious accommodations, travel worthy of the Davos set, and a reflection of glory. “Donald Trump is a celebrity—just like me!” Christie almost certainly thinks to himself. “Who is this Rubio punk? Why are his donors backing him and not me? Don’t they know who I am? Don’t they know who I have in my rolodex? Has Rubio ever taken a phone call from Bono? Slept on Richie Sambora’s couch? High-fived an NFL owner in that owner’s box?”

And so a few friendly phone calls from a second-rate reality TV star are enough to convince the supposed straight-talker to flip flop on his pledge to never support the David Duke-backed Donald Trump.

It’s sad. But then, the life of the C-list celebrity often is.
