Santorum won Oklahoma, North Dakota, and Tennessee. Gingrich won his home state of Georgia, and, once again, Paul won nothing. All of the above from various sites on Google which reference the Associated Press.
According to the RealClearPolitics chart Romney has 354 delegates, Santorum has 147, Gingrich has 87, and Paul has 54. To win the nomination requires 1144 delegates. In other words, Romney has substantially more delegates than the other three candidates combined.
