[worst-case scenario]

Part of the problem is that some of the health care meetings, like the one in Tampa, actually WERE SEIU information sessions for their members, to which they invited the Reps to speak. So the union members were there because it was bein held by the union to begin with.

This was the event Rush talked about on Thursday and encouraged people to attend:

Factually incorrect. Read your own link. It was an open meeting by the Congress critter with SEIU listed as a co host. It is an open public meeting that the Democrat party was inviting the public to attend. Then when the public DID attend, the Democrat party bosses had a fit.

Here is a picture of a Democrat party official slapping a peaceful protester at the very public meeting you wrongly claim was an SEIU event.
