Well, that's according to several media outlets. The NJ governor will hold a press conference at 10 a.m. to make it official - one more time. From CBS:
There were serious obstacles to a Christie run. The first was the fact that his position issues like climate change (he called it "real"), immigration and the notion of "creeping Sharia law" (Christie deemed such concerns "crazy" "crap") put him at odds with much of the GOP base. But even more important was simply timing: Christie would have gotten into the race less than three months before voters are expected to begin going to the polls.
