If I were advising them...
Santourm: Oklahoma - he needs to be somewhere he's going to win...
Romney: Ohio - because it's a state he needs to win to break the narrative that Romney is weak in the rust-belt... MA is a foregone conclusion
Paul: Probably Idaho or North Dakota
Gingrich: Georgia... duh
This, although maybe Paul should consider Alaska. Too bad he doesn't have the money to do one of those expensive internal polls that are never shared, to help him decide where his best shot is. Granted given the time zones, and presumably some desire to appear on prime time TV, maybe CST North Dakota might be best, unless Paul thinks he is slated for third there. Too bad too for Paul that so many of the roustabouts in the oil patch in ND probably are not registered to vote, although come to think of it, ND has no registration. You just show up and say hi, and vote! At least that is my understanding, unless things have changed. ND is unique in that way I think.
