I already know about the Democratic party and its history (which you dismiss entirely, for some reason, as irrelevant. Can't go forward without knowing where you've been and all that) as well as what it is today, despite what you seem to think. What matters is the clash along other lines, or ideologies (socialism-capitalism, liberal-moderate, moderate-conservative, etc), anyway, than any Red vs Blue debacle.
But, then again, I was always a huge proponent of Huntington
