gaseousclay, either provide support for your claim (that you keep making, over and over ad infinitum) that the NRA only supports Republicans, or else cut your nonsense.
Otherwise, please explain Harry Reid and the many other democrats who have received A or A+ ratings, and NRA endorsements.
Since we both know that if you look, you will actually find the NRA tries to ignore party affiliation and go by voting records with regard to gun rights, I suspect you will instead throw some barbed statements about.
What I'd prefer you to do is actually show cases where an established, pro-gun rights D received unfair grades from the NRA. I suspect you will only be able to find that such a D did not receive an endorsement if the R he or she ran against had at least an equally strong record.
And if you can't do that, admit it.
