I didn’t see it, but if McCain wins, the election will definitely not be over tonight. The Dems will begin litigation immediately, and I think the GOP is prepared for this.
IIRC, Lawyers from both parties are ON THE GROUND in all the battle ground states.
If Obama is losing, they won’t wait until tonight to start their catterwalling. The tales of voter intimidation, the legal challenges and anything else that will throw the election into an uproar will start by late morning.
Keep an eye out for that, esp. in the battleground states. Just like the 2000 FL debacle started around noon when it was reported that people wanted to vote for Gore, but voted for Buchanan instead.
The Obama campaign will want to make a stink early to rile up their voters out west.
