True enough, but it goes even deeper. Most people are a mix of being conservative on some things, liberal on some, libertarian on some, and collectivist on some. How do you appeal to a Hispanic Catholic Union member with a mortgage with a simple throwaway label like "conservative" or "moderate"? The labels aren't enough; you have to define what they encompass, or the opposition will define it for you.
The GOP needs to define what it is. So far, the responses I've gotten on this thread are A) it isn't the Dems. B) it is what it is. and C) it is whatever it will be.
Yep - define yourself, or live at the peril of the opposition defining you.
