I disagree, IDP. As you allude to in your comment, a Tea Party rally anywhere in the vicinity of New York or DC would be an instant opportunity for the OWC organizers. They would definitely infiltrate the event and disrupt it. I can imagine fist fights to be the minimal level of disruption...anything that would draw the cameras.
What is on our side is time and the time of year. There is a long way to go until the election and a very short time until truly nasty weather clears all of these creeps out of the northeast urban areas. Any prolonged rain or snow and it will all be over. When the number of protesters shrinks, the authorities (also sensitive to local voters) will clear the holdouts from the parks. That will be pretty much the end of the whole issue.
Seriously, for a lot of these idiots it's all about the media coverage. That's one of the reasons that they are driven to ever more ridiculous displays...if it's not new the media won't cover it...not for long anyway, people get bored seeing the same pack of dirty, smelly hippies marching around in a circle. The weather will clear out all but the hardliners. The authorities will clear out the rest. The media will leave, taking with them the magnet that draws the human debris.
Then we will have a break from this nonsense until spring. But when spring arrives the OWS will be old news and there will likely be little to no media available to cover it. The media only has so much in terms of resources and a lot of it will be involved with the primaries at that point. Summer will come and it will be too hot for a sustained protest plus again, the authorities will be motivated to keep their voters happy prior to the election and be reluctant to indulge the fetid hippies.
The spring would be the time to get the Tea Party back in gear as regards public protest. The OWS hippies will not be properly organized since a lot of them will still be in hibernation from the winter. A Tea Party demonstration on the Mall in DC would be very appropriate at that time, too, as it lines up nicely with the primaries...get people energized to throw out RINOs and stuff.
I'm still holding out for youtube videos of hippies knocked off their feet by water cannons, though. Perhaps Christmas will come early this year.
