Why is the Tea Party any better than, say, ACORN?
ACORN was supposed to "empower the disenfranchised." But it didn't. It is a corrupt organization that perpetuates the problems it's supposed to solve.
And that's how liberal programs and policies work.
The Tea Party movement, on the other hand, is a true grass-roots movement. It's attracting people because it's giving a group voice to those who feel their own voices aren't being heard.
