The bottom line is you have to nominate candidates that actually believe in something. McCain is the classic example of a guy with no true ideological underpinnings.

Yup. And may we never forget the "I would seek Al Gore's guidance on the global warming crisis" and "Andrew Cuomo would make a great SEC chairman" moments.
