It's not even certain if 50% of voters care to learn, or know, anything about sustainable economics, the size of government, or a responsible role in world affairs. BO spent $6,000,000,000,000 we didn't have to RAISE unemployment - yet he still won handily. If BO voters didn't realize their mistake before re-electing him, what makes you think they'll have a spontaneous change of heart?
We need some of those Dem voters to change their minds, but evidence is that they need loud noises and pretty colors to attract their attention. There is nothing in the Repub playbook that will do the trick, ergo they need a new playbook. If there is a better idea than the principles of libertarianism, I haven't heard it.
