Haha, I just wrote to my SNP MP about the GRR and how it had cost them my support, and I nearly mentioned the Poll Tax. I had quite enough to say though so I dropped that bit in the end.
I am now politically homeless though. As a left-winger, I can't vote for the Tories. As a feminist, I can't vote SNP, Green, or Labour (though I may still vote for my SNP MSP Ash Regan). I don't have to agree with everything a party stands for in order to vote for them, but this is a deal-breaker for me.
