For anyone question how networls are calling races with the GOP candidate in the lead---they look at the precincts that have NOT reported, check what the Dem did in the last election, and project, based on turnout/exit polls how that precinct is going to go this year.
Now, if the exit polls are screwy, these calls can be screwy.
Steele could be up, but it could be all GOP areas that have reported.
It seems a little strange though since the media's been saying all along how Steele was doing excellent among African-Americans.
