Maybe what we really need is somebody who understands basic fricking economics rather than someone who is a polished bull shite artist to tug at people's hearts.
That was Mitt Romney. However, with today's 24/7 news cycle and influence of pop culture, simply having someone who knows everything isn't going to cut it. If the GOP continues to nominate policy experts like McCain or Romney, they'll lose every election. Sadly, that's just the nature of the beast. Its not about your credentials, its about communication and PR. The Dems kill the Republicans in this regard.
The GOP needs someone savvy enough to cut through the noise and effectively communicate that the GOP/conservative message isn't exclusive to rich white people or ultra-conservatives. We've got to get our foot in the door first before it becomes a permanent minority party.
