REDSTATE has some interesting comments regarding Astroturf, and who is doing the astroturfing.
Like I said, the DNC/Liberals wing has never seen real grassroots, because they always create their own astroturf in a campaingn.
Nothing is real for them.
Even when real peasants have read the bills (more likely than the legislators) and have real, legitimate complaints. Since the DNC only has paid protestors, the rest of us who protest against then must have been paid as well.
Try Craigslist in your area. See what you find.
