As long as you have guys like Rush Limbaugh, Beck, etc. it's not going to happen.

We can discuss issues all we like, and they do factor into things more so than in the past due to how obviously we're in trouble, but at the end of the day this is probably the GOP's biggest problem. They've developed a reputation for extreme dishonesty (if not contempt for their 'base', look at that memo a few months back) and incompetence. As long as the face of the party are hacks like Boehner, Palin, Romney, etc. and loudmouth morons like Limbaugh or Hannity people will not want to vote
for them.
