6 p.m. and still raining

6 p.m.: Two hours before the polls close, and it is still raining. No, not nearly as hard as it was earlier in the day, but very likely enough to keep people inside - and away from the polls. What does that mean in terms of turnout? It likely will be low. Will that be enough to keep Arlen Specter's totals down and open the door to an upset win by Joe Sestak. Your guess is as good as mine.
