Counter-riff at 172 for your reading pleasure.
That being said, I don't think that it's totally out of the question. Especially if they receive a drubbing at the hands of the GOP two years from now.
I think the key to breaking the ironclad grip the radicals established after the '68 debacle and which has tightened incrementally during every succeeding election lies in greater turnout among those Democrats who have heretofore felt completely disenfranchised by the power brokers within their own party.
They need to cobble together a coalition from the ninety percent of black voters who comprise the Democratic base and the other faith-minded minority voters-who are still receptive to a populist, Dem. message-and join them to the remaining white Democrats who have been excluded from the nomination process up to this point.
If the Democrats can approximate the numbers that were reflected in the ballot initiatives/referenda dealing with gay "marriage", I think that they'll have a chance to resurrect their party.
