I have hit on this every way I know how, but it seems to fall on deaf ears among those who staunchly defend the Democratic Party. Interestingly enough, though, it gains a lot of "hear hear"s from Dem defectors who find themselves in the Republican or various third parties.
The fact is, Dems, your party is going down the tubes. With so much infighting, negativity and dissension, you virtually GAVE the presidential election to George Bush. By taking your party further and further to the left, you are alienating your moderates. I think so, virtually every Dem defector I've spoken with thinks so, and former Clinton advisor Dick Morris thinks so. But you continue to defend your tactics, somehow justifying yourselves in stating that we don't represent a significant voice in the Democratic Party. You are driving yourself further into obscurity and towards extinction because you WON'T LISTEN!
Years of experience in customer service has taught me that people who complain are the ones you want to respond to, because if someone complains, they're interested in continuing to do business with you, but have a legitimate beef they want tended to. While I can fairly say I've probably forever abandoned the Democratic Party, there are still disgruntled moderates among you that you should work to save.
Listen to these people, take what they have to say into consideration, and set about the hard work of reforming your party. Otherwise, I can virtually assure you that a Republican president will hold office in 2008 and possibly beyond, if a third party doesn't rise up and eliminate the Democratic Party altogether.
