CNN reports that attendees at McCain's "victory rally" have been cut off from the news. So unless they're checking their Blackberries and iPhones, they don't know the race is over.
Update by MissLaura: This was emblematic of the McCain-Palin campaign's approach to information: Dana Bash is reporting on CNN from the campaign party. The campaign party where they have turned off the news and are just listening to Hank Williams Jr. as every possible path to a McCain victory is cut off.
And then, right at the end of the segment, someone must have noticed CNN was discussing this, and suddenly CNN comes on the screens at the party.
Seriously, that's it in a thumbnail: Hide facts until someone catches you, then switch course like nothing's going on.
