I think South Carolina will be the first real opportunity for Marco Rubio to shine. Walker will primarily focus on Iowa and Florida, Christie will focus on New Hampshire and Florida, Paul will be heavy in all four states, and Rubio will try to focus on the more traditional GOP voters in the south.
I strongly object to you identifying "traditional GOP voters" as socially conservative Southerners.
As for the OP, I'd guess Cruz or Rubio.
Hey man, like us or not, your stuck with us.
I never said I didn't like you, but I'd say we are the more "traditional Republicans" of the two factions. I highly doubt Lincoln, Eisenhower and even Reagan would be championing the Tea Party.
Lincoln and Eisenhower don't embody anything similar to the modern GOP, and Reagan would likely be similar to a Scott Walker-level involvement in the Tea Party.
You seem to overcompensate for New England Republicans in most of these threads. You don't have to pretend like you guys run the GOP. If you did, your reputation would only decline due to the state that the GOP is in right now.
