From NRA's Chris Cox:
"We are a non-partisan organization, and we don't base any grade or any endorsement on a party affiliation. That's how we have continued to succeed, by solely considering how a candidate stands on the Second Amendment and the right to keep and bear arms. We send out candidate questionnaires to every candidate, and we look at public statements and the things they say in debates. We focus solely on the right to keep and bear arms, because that's our issue. Now, there are a lot of other issues that voters have to address, particularly in a year like this; they're looking at fiscal issues, they're looking at the health-care issue."
Doesn't seem that complicated to me. They consider only the one issue and it's up to the voter to take that, weigh it with the other issues, and make a decision.
And frankly, I resent it when an organization that should be focusing on one issue decides to try and be the final word on a wide variety of things. The AARP comes to mind as one of the worst.
