Jerry Springer is currently in that time slot on his other stations, and he is trying to negotiate with Air America for a spot on the network. Air America is not commenting.
I know that the Unfiltered morning drivetime spot has been replaced by Morning Sedition in the Seattle market. I can still listen to Rachel Maddow on XM Radio while I'm in the car. I used to listen to Morning Sedition over the internet. It's nice to have the choice over the air. According to the AP as of two hours ago, this is now a firm deal. They don't say which slot, but the morning slot makes sense.
Nothing on the Air America site yet.
Update: Now officially confirmed on Air America site, and by Rachel Maddow on the air. Springer will start on April 1. Still not sure which local stations it will affect.
