indeed, as i've said before (channeling SP Huntington), american politics is just an ongoing conversation about the appropriate balance at a given time among core values that are inherently intension with each other (eg, liberty v equality, limited government v security, etc.) Neither side's emphasis is wrong, or right, it's just their particular cocktail mix. And, just as you note a legit fear that perhaps modern R's increasingly don't recognize the legitimacy of 'equality' as a core value, so too i worry that D's aren't too big on liberty any more. In both cases, it's a huge long term problem, as the consensus over the universe of values is pretty much the only thing that defines an american.
