If you would read the NRAs information, you would see that they are a SINGLE topic group. Harry Reid does indeed have a good track record with gun rights; despite the fact that is pretty much against the rest of our rights. So they supported him against any democrapic opposition that he might have had; what have they said about his Republican opposition?

Edited to add: I'll have to do further research before I comment on the Colorado cantidates issue; until I see for a fact that the NRA is supporting an anti gun dem over a pro gun repub, I won't comment on that.
