I had considered writing an article about this question, and came up with a ‘House that Jack built’ string of consequences. If this storm is as bad as they say it will be in the East, the direct impact will be the loss of power in the region, and downed trees. That in turn will cause a shift from automated poll-counting to the old-fashioned paper ballot counting. That shift in polling technique will mean really long lines at the polls (paper polling is lots slower than automated polling) potentially at a time when people will be more worried about restoring power and finding food and getting back to work. The effect to the election will be lower voter turnout. With lower voter turnout, the weighting on the results will go to those who took advantage of early voting.
But the East and North East are not the only regions that will be affected. We are beginning to hear calls for three to four feet of snow next week west of the Appalachian Mountains. Those regions will also be affected, and likely with the same consequence – lower voter turnout.
Given all that, the results of the election will depend on who is more determined to get to the polls under those adverse conditions. The full answer would depend upon some knowledge of how the early voting is going in those states that will be affected. That may well make the difference. No matter who wins, we’ll be able to blame the next four years on Sandy Frankenstorm and The Great Pumpkin.
