Nick - I disagree with your premise that republicans are the only ones that are trying to eliminate the vote for women and minorities. There are unethical people on both sides of the aisle. Many elected republicans have worked with democrats to get things done and that is why there is such anger at the "establishment" on both sides. I agree that there are some republicans who are in office to further their own agenda, but the same can be said for some democrats as well. 
I do not think that saying that republican/conservative voters are dumb and blind adds anything worthwhile to the debate.
