This is a party that doesn't believe in science, whether it is evolution or the big bang or scientific polling -- hell they have problems conceding there is gravity.
Their leadership was as enthralled of miracles over reality as much as their base.
What fucking reason is there to think they are going to suddenly accept actual voting?
Right now the GOP is thinking, well the minorities won't turn out in 2014 so no need to change now.
If you WANT them to change you better find a way to make sure your base turns up in non-Presidential election years. IF that happens, THEN they'll have no choice.
But until then? Nothing, they'll just keep hoping for the worst -- and doing everything in their power to MAKE the worst come about.
