Is this astroturf or grassroots?

I thought if any organization participated in helping get people to townhalls, that it was astroturfing. Or does that only apply to the right? Because I got this in my email box yesterday:

Dear MoveOn member,I’m a MoveOn member like you, and I’m working with the local MoveOn Council to organize an event tomorrow in Warner Robins to make our voices heard for real health care reform.The event is on Monday, Aug. 24, 2009, at 5:00 PM in Warner Robins. The location of our event is: Homer J Walker Jr Civic Center.Here’s the event description:

Jim Marshall, a Blue Dog Democrat, will be having a Town Hall on Healthcare at the Homer Walker Center in Warner Robbins. As you may know, he is waffling on whether or not he will support public option. A group of us MoveOn members have come up with a line of questioning that will punch through his cynicism and get real on this real issue. Bring yourselves, a positive attitude, a “public option means more choices” sign, and your hope for a better America.Please gather at the Center at 5pm so we can submit our questions early. Look for the women with the 7 Red Ballons out front. We will be with MoveOn. Again, look for the 7 Red Ballons!

I hope you can join me and other local MoveOn members. Click here for more details and to RSVP:Yes, I’ll be there on Monday at 5 p.m.Sorry, I can’t make it.Thanks for all you do.–Kimberlyn C., MoveOn memberP
