You forgot to mention Birch and Saddler, even though they're kinda hiding in the back of the group.

As for the Dems?  Sure looked like Justin Parish slightly to the right of front-and-center in that photo.  I think the shot itself is more telling, like perhaps the Dems told Marc Lester that he could do his job so long as he didn't actually walk in?  Reference another commenter's remark "More than a few people in the photos look a little uncomfortable, as if they are thinking 'Why is that person taking pictures?'"  My experience with the Dems is that they'll give me lip service if I pay to attend one of their events, but otherwise the gloves are off.
