"His supporters raised the cash on November the 5th to commemorate Guy Fawkes."
Therefore your complaint is not valid. He never said the campaign ran this.
That's not actually true. Here on these forums people have discussed violent overthrow of the government if Ron Paul's campaign doesn't succeed.
He states at the beginning of his program that we need to be worried about threats that are not only foreign but also domestic. He says almost everything to suggest that people in the campaign are terrorists.
Personally, I think it is worse to make a big deal about it, one should just let it go.
However, to say that this is not a hit piece and a distortion of the facts is just beyond me.
