You’re very right — as long as the Republicans getting off work go and vote, these early exit polls have no meaning.
They are designed to demoralize, and if our voters don’t get demoralized then the media trick has failed.
Yes context would be helpful -- Drudge frequently posts items he labels "flashbacks" to contrast a current situation with a previous one.
In this case he should post a "flashback" to the 2004 election, in which exit polls showed Kerry winning handily.
I probably didn't need to remind FReepers of that ... most of us likely remember that nerve wracking news quite well! But things changed when the REAL polls closed. No President Kerry.
Moral of the story: Don't trust exit polls. For whatever reason, they are nearly always biased against Republicans.
