When will Limbaugh/Hannity start jumping ship?

[JohnnyCougar]

Their credibility rests with Bush getting re-elected. If Bush goes down in flames, however, they will look like jackasses, and they know it. Especially if this administration gets prosecuted for war crimes and such in the aftermath. My guess is that they will do everything in their power to get Bush re-elected, but if it looks hopeless, they will jump ship to save their credibility and probably endorse Badnarik or Preoutka. Any thoughts?

On edit: I am specifically talking about the "W" ship, not the broader RW propaganda ship! I think there is a point where carrying W's baggage will be burdensome for the RW.
