Be it right or left, if you are requesting not to have media available, then you are a bit nervous of the outcome of the debate.

That is the true purpose of why their is a ban on the audio/video of some who are debating. And for the record, I have no doubt that the Repubs would do the same if in the same shoes. As of late, I see very little difference between most.
When you look at spending, it did not happen alone. When you look at pork, the right are guilty as well. In fact, I find them far more guilty. They were elected to be a leaner working government, not an open check book.
