That's probably good for HRC -- easier to turn out those old ladies that way. I'm not being mean -- she has to turn out a lot of little old ladies. And probably good for Barack Obama -- easier to turn folks out, generally, when the weather is nice. And if nice weather = higher turnout, then it's probably good for Mitt Romney, too. But also for Mike Huckabee, if he's relying on a lot of first-time caucus goers.
Thank goodness we're not in 1971: on January 3, 13 inches of snow fell. Last year, and the year before, the weather was clear and mild.
