Hugh Hewitt has discussed it. He's skeptical. Powerline, Instapundit have brought it up.
You don't ask the question unless you know the answer.
I saw "the toe sucker" Dick morris on O'Reilly last night and he said some thing would drop in the last week of the race. It would probably be this or the rumored video of sKerry burning then urinating on the flag.
I am sorry to say that IMHO, in today's America, the MSM is more insidious than Pravda was.
I think this is a total dead end. It MIGHT make a little difference if clear info came out the last weekend of the campaign with ads that said, "Kerry Lied," but probably not much.
