Nonsense. It's called exit polling and waiting for enough results to verify them. The chameleon won Virginia 60/40 over RuPaul but the networks couldn't call it for quite awhile because not enough returns had come in to verify the exit polling. There were enough districts the loon had done well in to force a delay in calling the state for Willard.
People really need to quit with the silly conspiracy stuff. Santorum apparently won decisively enough in Louisiana exit polling that they didn't need to wait to make the call.
It's hard when you hear supposed news anchors discounting the entire South in order to prop up Romney.
Also, I keep seeing and hearing from Ann Romney now with the "can't we all just get along" speech. No more name-calling, let's focus on the issues. This from the wife of the guy who started the scorched earth campaigns
