You often hear the left trumpeting the "Tea Party" as just being a facade behind rich Republicans, who are the real power behind the operation.
No matter how many citizens are interviewed at the gatherings, that remains their thought.
Why? Because that's how they do it. So they expect Republicans to do the same.
They pay people to protest, so the other side must be paying people and helping them get to D.C.
Just because you love astroturf doesn't mean the other side does too.
