I was a write in member of the Dems for a few years before joining the ALP after the October election of 2004.
I liked the Dems policies and back when I joined them I considered their 'watchers' role to be important.
I moved the Labor because I realised I despised the coalition government and now was the time to pick sides.
The Greens and the Dems appeal to the same educated left of centre base. Least that's my reading of it. And in the 2004 election the Dems unfortunately preferenced against the Greens in most senate tickets - since they were largely appealing to the same small segment of the populace.
The Greens are on the ascendant. And I wish them the best of luck. So maybe the Dems, whose policies are pretty much in line with the Greens, should consider a merger. Become the Australian Democratic Greens party or something. Present a united educated leftist front instead of having to battle each other and strip votes away and allow dickwads like Fielding to get up.
Of course I an an ALP man now. But if someone had to have balance of power in the Senate I'd rather it be Greens and Dems that the Coalition any day of the week. And a merger just might help that happen if the ALP are unable to get control of the Senate (which I doubt).
