What the heck is taking them so long? They have been yapping about this for months. Get on with it! Hurry up and crash and burn. The only ratings boost they will get in the first few months will be from conservatives tuning in to find out how lame it will be. That's why they plan to parody Rush, to go after some of his audience and probably to draw next-day responses from the Maha Rushie.
Reminds me of a song: "What shall we do with the liberal radio, what shall we do with the liberal radio ... take no [Kerrying] notice of them, take no [Kerrying] notice of them ..."
They didn't dare start too early. Their money will likely run out on election day.
