In the context of an election, heavy rain can mean a low turnout for the Lazy (aka Democrats).
Or are you not aware of the election today...
Further, the weather map shows heavy rain in the South - worst in Southern Louisiana spreading up into Arkanasa, Tennessee, Mississippi, Alabama, Georgia and Northern Florida with the Carolinas and the Virginias getting some as well.
Minnesota, Wisconsin and Northern Illinois are in for snow.
Some precip in the Northeast is also expected but not as much as was earlier forcasted.
There is also a chance for rain in Oregon and Washington but who the hell cares (electorally speaking)?
