This will be tricky for the MSM to cover. It is really a lose/lose. They can't really play the clip because it is just so offensive on its face. If they go with the "joke" claim, they basically have to say that Kerry called the President of the United States stupid. That will appeal to about 3% of the population.
Just listening to the top of the hour news(Fox), they did play the clip and then reported on Kerry's press release attacking Republicans and Tony Snow, specifically.
This presser should be very interesting.
Where IS the press conference?
