Much as I dislike to say so, I agree with the NRA in the instance. If you have an organization the purpose of which is to promote seatbelt laws and use, it would be inappropriate to back the opponent of a candidate who supported seatbelt legislation because the opponent favors offshore drilling. If the NRA didn't support incumbents who voted the right way, the organizations clout would disappear. If, in this case, they back his opponent, then they look like nothing more than a puppet of the Republican party.
