That was completely scripted. Sheehan has been used and brainwashed by tha antiwar left.
For a real good laugh go to DU to read some of their 24/7 Crawford postings. Not unique is the claim that this is the opening shot in the new revolution, our Ukraine, etc,,blah,blah,blah. And of course one of my favorites "Light a candle for Cindy". Really over the top and funny as hell. And of course if even 1% of the asshat DUmmies who claim they are going there immediatly actually show up there will be traffic jams in the area.
