OK, my own answer.
Pretty straightforward really. I've almost always voted for the Green Left, which had been founded just as I got old enough to vote (1989).
(The Green Left is to the left of Labour, be it more individualist/libertine, and to the right of the Socialist Party. Its always gotten in between 3,5% and 7,5% of the vote in national elections and usually does better in local elections - especially in big cities with a university ; ).
In local elections I've voted other things, too - twice "Livable Utrecht" and once a party called Grass (which had two programme points: more trees in the city and legalisation of soft drugs).
I also refused to vote Green Left some time in '94 because I was angry at their choice of national leaders. They'd decided to make the no. 1 spot a "duo-job", and in a referendum among party members the later (solo) party leader Rosenmoller + partner were defeated by the former communist Ina Brouwer and Moroccan community leader Mohammed Rabbae. Luckily Brouwer dissapeared quickly after that and I could come back "home".
I finally became a member in '99, when the party came out in favour of the war against Yugoslavia: the newspapers were writing about how many angry pacifists were suspending their membership, it seemed the right time to enlist.
My whole fit about Brouwer had been ironic really, considering my very first vote was in the "shadow elections" they stage at secondary schools when there are national elections. My school was pretty off-centre as it was, but I still was the only one to have voted Socialist Workers Party.
(I went to a Montessori School. The biggest party there was the rich-people's right-wing-liberal VVD, and the second biggest the Pacifist Socialists ;-) )
My mother was on the Labour list some time, and I probably wouldve voted for her, but I dont think I was old enough to yet. I voted for her best friend on the Green Left ticket in my first local elections, though. Funnily enough, my father - who in the early 70s had been voted out of the local Labour board because he was too radical - almost made it back into the local council last year, also for the Green Left. You can guess what my "political education" was like, I think
