Somewhere (and I can't find it anywhere) I read about some lefties who recently went to visit their Representative somewhere in the northeast. They went into the office and refused to leave even taking pictures of the President off the wall.
I doubt they will try that at DeLay's office. A well-equiped security firm shares the building with them and the Webster police are going to be out in force. Both are known for taking a dim view of troublemakers (i.e. they don't give a fig about the ACLU) - especially liberal ones.
