It would be interesting to see what % of signs were whacko birther related, what % were racist, what % were nazi comparisons, etc.

Clearly an organization that wants to have some credibility should have set rules that such signs were forbidden, and would be removed. Sure, they’d have trouble actually doing so (particularly if the signs were indeed a significant %), but the minimum requirement is to make a serious attempt at removal, IMO. If they really intend the message to be “less government” you’d think they’d care that the nut jobs dilute that. Course if the message is really birtherism, etc …
