I'm not sure all the occupiers would agree with your graphic. Sure there's polotical groups trying to co-opt the Occupy movement--just like the group that ruined the Tea Party for me. Once the social conservatives came, the tea party turned into a branch of the GOP. That's when everyone stopped paying attention, because that's not what it was all about.
Similiarly, if the Dems co-opt the occupy movement and make it about some union agenda or whatever they're trying to make it, it'll fizzle the whole movement. That's why these things never work. no change can happen when all the sudden it becomes some partisan issue.
