They should have asked the Supreme Court to stop the polling on Saturday.
Speaking of which, what happens if Renquist (or any other justice) passes away, a critical election decision is brought to the court, and the result is split?
My guess is that an eight-person Supreme Court will tend not to take any critical cases on appeal.
One theory is that they Supreme Court acted as it did in 2000 only partially out of partisan politics. The other rationale could be that they feared a constitutional crisis and anarchy, so they took charge. If an 8-person court refuses to hear any election case, it might help confirm that hypothesis - they wouldn't be able to guarantee a clear decision.
Anyway, sorry for the sidetrack. The shift in the Fox poll is pretty dramatic.
