Let’s look at these West Coast states. Even though they’re still voting in California, obviously Obama is going to win it (55). And equally obviously, he’s going to win Washington (12) and Oregon (7), where neither side even bothered to spend a dime. Throw in Hawaii (4). Those 78 votes haul Obama up to 260. That’s something to keep in mind for election night: Whatever Obama’s number is at 10 pm Eastern, add those 78 EV’s—they’re a mortal lock, and a hefty insurance policy. If he wins Nevada (6) and Colorado (9), it’s over.

In other words, Obama can lose the big Eastern four—Ohio, Virginia, North Carolina, and Florida: all of ’em!—and still be reelected.

And barring some huge cataclysm, he’s not losing all four of those states. If he wins even one—say Virginia, the smallest of the four—then Romney has to win Colorado, Iowa, and New Hampshire; all possible, certainly, but all states where he has been behind, narrowly but consistently, for weeks or months.
