From “How Bad Does the GOP Need Chris Christie? Really Bad,” Michael Tomasky, The Daily Beast
“[The GOP has] reached the point where they almost have to have a Northeasterner like Christie to run for president, just as they had to settle for Romney last time. They’ve let their party go so far off the deep end that practically no Republican officeholder from any other region of the country could appeal to enough moderates in enough purple and blue states to win back the territory the party ceded to the Democrats in the last two elections.
“Remember: the Republicans come into the next presidential election with 206 reliable electoral votes from states their nominees have won at least four of the last six elections. The Democrats’ corresponding number is 257 (just 13 shy of the victory threshold). These tallies leave five states on the table: Florida, Ohio, Virginia, Colorado, and Nevada. …
“So the establishment isn’t going to give up on Christie easily. And of course he can enjoy the benefit in these next weeks and months of becoming a more sympathetic figure to the hard right than he’s ever been, because all he has to do to please that crowd is carry on about how the East Coast liberal media are trying to do him in. And it may just work.
“But ultimately, facts are facts. And if the facts finish him [Christie] off, and the GOP is stuck with Cruz-Rubio-Paul, or even a right-wing governor like Scott Walker, the establishment will be reaping what it’s spent the Obama years sowing: a party that cares more about feeding its base’s fever-dreams than being nationally electable. And that’s where things stand, as Christie begins a term that there’s a sporting chance he may not even be able to finish.”
I’d say much more than a sporting chance. I think it’s a question of when, not if, Christie will resign.
