Frontloading HQ: Santorum Can't Get to 1144, and neither can Gingrich

FHQ has been saying since our Very Rough Estimate of the delegate counts a couple of weeks ago that Romney is the only candidate who has a chance to get there. But, of course, I have not yet shown my work. No, it isn't mathematically impossible, but it would take either Gingrich or Santorum over-performing their established level of support in the contests already in the history books to such an extent that it is all but mathematically impossible. Santorum, for instance, has averaged 24.2% of the vote in all the contests. Since (and including) his February 7 sweep, he is averaging 34.7% of the vote. That is an improvement, but it is not nearly enough to get the former Pennsylvania senator within range of the 1144 delegates necessary to win the Republican nomination.
