I doubt that since most people haven’t even seen the movie. I certainly never associated Guy Fawlkes with the movie, indeed I am only vaguely aware of the movie. How do you know Paul choose the day because of Guy Fawlkes? It could be just a coincidence. Every day of the year is a holiday somewhere in the world, and frankly choosing a british holiday seems a bit obscure for an American politician, assuming he is trying to make a statement. Most people simply won't get it.
Actually, Paul didn't choose the day. He has a campaign and a zillion or so others have a similar campaign. They chose the day, not him nor anyone in his official campaign staff. About the only thing they have in common is the desire to elect him President. That may not happen but in the meantime we're being treated to a magnificent display of grass-roots activism. It would be a shame to waste all this energy.
