Organizing principles

I ported my last entry (What do Democrats stand for?) over to my diary at Daily Kos and added a poll asking people what single principle most unites the Democratic party.
If you’d like to vote over there, visit the poll there and help me sort it all out. Of course there’s an Other category since my list of choices is probably for from exhaustive and biased and limited by my own perspective. If you choose Other, post a comment over there to say what you think the unifying organizing principle of the Democratic party is (or should be).
