According to a recent survey by the Weather Channel, 35 percent of undecided voters say bad weather will have a “moderate to significant” impact on whether they vote, compared to 27 percent of Democrats and 20 percent of Republicans.

Though those numbers appear to favor former governor Mitt Romney, Hudak says team Obama should be praying for rain.

“Obama has been effective at getting voters to vote early, so anything affecting turnout on Election Day is likely to be bad news for Romney,” he says. Voting during a storm is also easier for urban voters—a group that overwhelmingly supports Obama—who often have a shorter distance to travel to polling sites than rural voters. “It would certainly set up a benefit to the president if a natural disaster did interrupt voting.”
