As a non-USA-citizen, I don't have any stake in the outcome, but I'm really curious to see how this affects Christie's run for the White House. Is this a big enough problem to derail his carefully crafted "Pragmatic, bi-partisan, get stuff done" persona, or will it blow over?
My personal take, FWIW, is that he either knew and is lying, or he didn't and is a schmuck because his whole team leadership lied to him for months and he didn't catch on. If I was a voter I would be asking myself, "What if this guy is elected president, and then one day gets mad at me?"
