Question about the Tea Party Protesters?

Why is it that the most vocal "Tea Party" protesters and Anti-Tax activists are often those who pay the very least in taxes?

While I do understand that many small business owners also form the ranks of these groups, they are far from the vocal (voir : nutty) groups I was referring to.

To be honest, if anyone should be angry, it should be those rich, coastal "liberal elites" from the likes of New York, Silicon Valley, L.A, Boston, etc, afterall, they are the ones who will be hit hardest.

And remember, "Keep government hands of my Medicare" ;)
