Is your insinuation then, that conservatives show up to vote much more than democrats because these conservatives are mostly retired, white folks who are convinced that the darkies are taking over?
Most who vote Republican know what they are voting on. You can't drag homeless people off of the train tacks, give them a ride to the polls, and give them five or six cigarettes to vote Democrat and expect them to know what they are voting on.
A conservative will climb a mountain of rocks to get to the polls if necessary. That's because voting is so important to them. In my opinion, voting should take some effort because our country would be so much better off if only informed people voted. If it were up to me, you would have to take a simple test as well before voting. Nothing too hard, just questions like who is the Vice President? What party does he or she belong to? What party leads Congress, the Senate?
If we could create such a law, the Democrats would have a shit fit. They rely on people that only know to vote for anybody with a (D) next to their name and nothing more. And this is why they are so upset over Voter-ID. It has nothing to do with the competency of blacks, it has to do with discouraging people like the Obama Phone and Obama Money ladies from voting.
