I had the same experience in Florida. TWO Dem attorneys showed up as poll watchers and basically set out to intimidate the voters by setting up their table at the door so they looked official, as though people had to go see them first. I complained to the election officer and he made them move to the side where the other poll watchers were sitting.
We also had a very honest election officer, and he ran the polling place very well.
And, yes, the Dems brought busses and busses of folks from black churches, nursing homes and even from the local state home for the mentally disabled.
Well maybe I should feel some relief then at the idea that one of them went 100 feet from entrance to building (supposedly). I have no idea of what they were doing out there though - probably campaigning.
