Where any persons alowed into the meeting carrying pro-McCain signs?
Was this "public meeting" in some Rented place where exclusive use by McCain et al could be assumed where someone could reasonably suppose that there was no absolute priviledge of carrying in opposition signs?
Regardless, unless the sign was unusually large or gaudy and reasonably interpreted as pre-emptive of audience and press attention, the saying Bush-McCain is quite familier and commonplace, and calling such attention to it by expelling it's carrier would seem counterproductive and foolish by his staff.
Sometimes Politicos genuinely regret some doofus act by their staff. Othertimes, I suspect, they simply give lip-service to "crocadile tear" regrets.

One should be careful in reviewing such evnts to look at the total picture and not some fact not described in sufficiently adequate context. I'm sure we'll be hearing more of these by both sides as the Election rolls on.
