Where are you getting the NRA spent little? I read they spent a lot. Plus, some independent groups didn't have to disclose how much they spent where as the candidates did. No one knows how much those spent.
And Enyon is far from the exception to the rule. There are many like him. Reasonable. But there are also Ted Nugents, and those are the nutters.
Once again, the district agreed or were split with the actual rule changes made regarding guns. Why were they recalled if they passed laws they don't disagree with in their districts, in your view?
