That was my thought as well IDP. It's like the infamous Daly machine to the Kennedy campaign: "How many votes do you need?"
Since the 2000 debacle, I've been of the opinion that no polling information should be made public until after all the polls are closed and ballots tabulated. The Left have manipulated the system into a win-win prospect. If they manufacture enough votes to win, then they win; if by manufacturing votes they erode public confidence in the electoral process, they win. Their whole MO, the one common denominator to everything the Left is involved in, is the effort to erode confidence in and the legitimacy of the current system. They want people to be cynical and dismissive of it, because it makes them amenable to the "reform" they trot out on cue.
