MSNBC:

One day after Sarah Palin announced her bus tour, a group sponsoring a Memorial Day weekend event she plans to attend said they never invited her.

"She wasn't invited. We heard yesterday she came out with a press release she was coming to Rolling Thunder," Ted Shpak, national legislative director of Rolling Thunder, told "Andrea Mitchell Reports." Shpak is one of three members of Rolling Thunder's current leadership who says he had no idea Palin was coming until it was posted on her website....
"She's not invited to speak. We're not endorsing her ... (but) we can't stop her from coming to ride, if she wants to ride," Shpak continued...Shpak says Palin's attendance "is a big distraction" and that his "phone has been ringing off the hook" ever since she announced her intention to attend the event.

Did she just assume she'd be welcomed with open arms? That seems like kind of an enormous detail to just leave up in the air; who's doing the planning for this tour?
