Most of my family were (parents, grandparents, aunts & uncles etc). I've got huge respect for Ken Clarke, John Major etc. Sarah Wollaston (I know she's in the LibDems now) was a close friend's MP and I've met her at a local church fete when she was still Tory. I liked her enormously.
There was a rabidly anti-Semitic great-aunt who was in the BUF known as Mad Molly by her family. She died in the 1960s and was completely unmourned because she was so vicious.
She never got invited to family weddings or anything, even out of pity or duty because she'd turn family events into a chance to rant about conspiracies headed by a 'World Cabal of Jews'.
I only came across her once, when I was a child, and she terrified me because she was shouting at my mother on Regent Street outside Dickins & Jones (we'd gone to the sales) calling her a race traitor when she saw her because one of her best friends at school was Jewish. As a direct result extremists are always people I've shunned, whether SWP or BNP.
I'm an archetypal floating voter. I've voted Green in the European elections, mainly because my maternal GM and GF were really worried about the environment and I knew because of the PR system that vote would count. My GF took me to the local river (quite small tributary) and showed me all the detergent foam on it and how all the trout had gone.
When there have been elections for MPs & local councillors on the same day I've often voted across the spectrum according to who's standing and their individual stance on various issues. There's one local Labour councillor I've always voted for.
