Chris Christie is a brash east coast guy who is good at trolling, but you can't really trust him, and you wouldn't want him to lead anything.

If Christie's attacks prove to be Rubio's undoing, then he will have fucked the Republican party for four years. If Trump or Cruz get the nomination, Hillary wins. However, Rubio was 5 points ahead of Hillary in the latest poll averages.

Christie has no chance, so you can't even say that he has to resort to this in order to win the primary. It's already over for him.

With that said, Rubio should have been prepared for something like this, and had better comebacks ready.
