Christie wouldn't win one state, god he's terrible.
You have a point, though he would probably win
some states, most notably Wyoming and Montana. He would probably/almost certainly win states like Utah, Oklahoma, Idaho, Alabama, Nebraska and Tennessee as well. I also think he'd be (heavily) favored to win both North and South Dakota. And he'd probably win over Hillary in at least a handful of other states as well. So he'd probably win between 15 and 20 states in the end (possibly more), though that wouldn't even be close to enough to win the Electoral College. Against anyone but Hillary, he'd stand much greater chances though.
