Are we nearing critical mass on the townhall "protests?"

The crazy is clearly out of hand at these townhall "protests," and the crazy (and the misinformation) is now becoming the main story of the protesters.

However the beginnings of the appearance of concealed guns at multiple "protests" and the increasing likelihood that we may see something REALLY out of hand at some of these events, are we about to see the "responsible" politicians start to back away from the movement?

(Especially when you have FoxNews and some of the radio figures warning people about their need to protect themselves from "union goons.")

This feels like it could all turn so violently ugly, and I think many figures on the right are starting to see that. I would expect over the next few days to see some efforts at distancing and deniability across the right wing spectrum.
