A reminder of the official delegate count, as seen by the RNC: Mitt Romney 73, Newt Gingrich 29, Ron Paul 8, Perceived Frontrunner Rick Santorum 3, Jon Huntsman 2.
Some of the caucuses so far have begun the process of selecting delegates to the national convention — the local caucuses select delegates to the county conventions, who select delegates to the state convention, who select the delegates who go to the GOP convention in Tampa. Some media organizations have projected the likely allocation of the delegates based upon the first round of the caucus.
Using this formula, the AP has Romney at 105, Santorum at 71, Gingrich at 29, Paul at 18, and Huntsman at 2.
