Mitt Romney is the candidate of the Northeast, the industrial Midwest, and the Mormon West. Rick Santorum is the candidate of the Plains states and both the upper and lower South. Newt Gingrich is the candidate of—well, not much.
Yesterday’s primaries in Alabama and Mississippi, the white South’s dankest backwaters, produced clear victories for Santorum and ended Gingrich’s already-modest hope that he could at least be the candidate of a region. Barring some upheaval, it’s hard to see where Gingrich could win another state. Last week, he ran fourth—behind Ron Paul, dead last—in five of the ten states holding Super Tuesday contests. Like most of the states still to vote, those five were all outside the South. If Gingrich stays in the race, he’ll likely be dueling with Paul for the distinction of coming in next to last.
