I'm not sure that they do. They haven't endorsed for the general election yet, have they?
As for generic support, they should support Harry Reid. For as detestable as he is on most issues, on the NRA's SINGLE issue, he has singlehandedly acted as a barrier to any gun control that the Democrats can bring to the table, being the majority leader. But I don't see where the NRA says "vote for Reid, NOT Angle."
Yech. I feel disgusted for defending Reid. But if you're a single issue organization, which the NRA is, sometimes you have to.
You’re right, but that’s why I get frustrated with single-issue organizations. They fail to grasp the big picture.
