What would Christie's strategy look like? Neither SC nor NV are particularly fertile grounds for him. On Super Tuesday, Massachusetts might be a good fit, but the rest of the states are either southern or are places like Vermont or Minnesota that wouldn't take kindly to Christie's super-urban demeanor.
Christie's hope has to be for Rubio to drop out and be seen as the best alternative to Cruz and Trump. I agree the path for him is very narrow.
Mencken is also right that Republican officials did a very poor job designing the schedule if their goal was to secure a moderate, Northern establishment nominee. I'm gunning for Cruz at this point, so I'm glad they screwed up.
