I don't think the group are politicians at all, but conservative minded every-day people who are fed up with the direction the country is being taken, fed up with politics in general and feel that something needs to be said and done to turn the country around to embrace more conservative values.
Yeah, you bet that politicians will attempt to use this movement any way they can to gain points for their side, and, some side-show types, such as Palin and Beck, will sure enough do their best to make a buck off of the movement.
