Then i'm suspecting your life is either short, or has been relatively superficial compared to my own. I have watched the NRA slowly strangle all opposition to it's ideas over the course of many decades.
Do you know how they did it? When they were BACKSTABBED by a Republican, they threw all their weight to the Democrat. When they were BACKSTABBED by a Democrat, they threw all their weight to the Republican.
You may not grasp this concept, but it is called "Whipsaw." It is how a small minority can CONTROL the outcome of an election and thereby get their way as if they were a majority.
So you think the idea is insane? I think you haven't been watching enough history or politics to grasp why it is exactly the right thing to do.
I reject your premise. The actions of a single issue lobbying group do not easily translate to political control among the two major parties. A young Democrat elected to the Senate will still be in office when you and I die, and he will never stray from the Democrat agenda.
