I'm not a tea partier, but I agree strongly with their ideas of getting the budget under control. While I may not support the tea party 100%, I think their ideas should be part of the discussion. As for racist signs, from what I have seen in online forums and recent polls Herman Cain is the leading candidtate (e.g. 77% in the recent IL tea party poll).

But for OWS, they need signs all right, but in a Bill Engvall "Here's your sign" kind of way. Don't even know where to start with this, it's just too goofy for discussion:

The American Dream has been stolen from the world. Workers are told that they aren't allowed health care, shelter, food. Students are told that they aren't allowed jobs, and that they will be in debt for the rest of their lives, unable to declare bankruptcy. The 1% has destroyed this nation and its values through their greed. The 1% has stolen this world. We will not allow this to occur.

No one has ever told me I wasn't allowed to have food and shelter. They did however mention that if I take money from someone as a loan that yes, egads, I would have to actually pay it back.
