In Super Tuesday results, Romney won 6 states (Massachusetts, Vermont, Virginia, Idaho, Alaska, and the big prize of Ohio); Santorum won 3 (Oklahoma, North Dakota, and Tennessee), and Gingrich won 1 (his home state of Georgia).
In terms of delegates, with some states awarding them proportionally and others “winner-take-all,” Romney picked up 212, Santorum 84, Gingrich 72, and Paul 22. So Romney got 54%.
Altogether at this point in the campaign, Romney has 415 delegates, Santorum 176, Gingrich 105, and Paul 47. Winning the Republican nomination takes 1,144. So Romney has twice as many as his closest competitor and is just short of being halfway to the nomination.
(I would like to report that in the two-man race in Virginia, where I voted, Ron Paul took 40% of the vote, far more than anyone expected.)
