Kevin McCullough links and comments on Walter Shapiro's USA Today column, analyzing the Democrats' dilemma. Shapiro says that the Democrats are really four parties in one, united only by opposition to the Republicans. He names the four factions as "the Party of Cultural Permissiveness," "the Anti-War Party," "the Party of Economic Justice," and "the Status Quo Party." "Status Quo Party" refers to the Democrats' habit of frightening certain constituencies into voting against any change to their pet government programs.
I think he's missing one faction, somewhat related to the "Status Quo Party." That's the "Perks and Power Party" -- the faction devoted simply to doing whatever is necessary to remain in power and enjoying the fruits thereof.
My feeling is that the "Party of Cultural Permissiveness" is on the rise in the Democratic Party, and that if you scratch beneath the surface of many in the other factions, you'll find that cultural issues ultimately motivate their opposition to the Republicans on the war, the economy, and government programs. Increasingly voters sort themselves between the parties based on cultural issues more than any other issue.
