>> The irony is that the NRA is more likely to endorse Travis Childers because he is the most conservative between Cochran and Childers. <<
I think you’re wrong. It’s my understanding that the NRA looks ONLY at votes on gun issues. Cochran already has an “A” rating on that score. Even if the NRA also rates Childers with an “A” — based presumably upon his answers to the NRA questionnaire — they still will endorse the incumbent, as a sort of “reward” for his past votes.
