I think the ‘script’ is already written...maybe three solid individuals or paths written out, and Trump has some day selected at the end of the month. Course, he may want to do the Senate hearings in January, with a larger number of GOP Senators around.
Christie’s name being thrown around...I suspect...is simply to drag up drama and speculation. CNN will waste tens of hours talking about the positive nature or negativity of Christie, then wake up to realize it was never going to be him.
With AZ and FL probably gone, the additional GOP senators will total exactly one, still below what we had when Sessions was senator.
