Yeah, but you can't count on moderate people to get out there and smear and spread rumors and 'lie for truth'. Moderate people stay home and watch TV.
The people you are talking about are the ones that get out there and do their dirty work for them. Maybe they are kooks, but honestly what works, works. You can bet Republicans wish for as many kooks like that as they can get. Think of how much you'd have to pay someone to devote the time Col Gene devotes for free.
As ugly as the next election is going to be, Republicans had better start wooing the kooks themselves.
