But what you don't seem to get is ideology. Your beliefs are the same, year in, year out, surely?
Mostly, yes. My values are fundamental to me.
Therefore, you vote for the party that shares that ideology (or as close to it as it can be).
Mostly yes. As far as I can know that an organisation comprised of people I've never met can share my values.
You stick to your ideals regardless of who is temporarily in charge.
Absolutely not. The Leader not only leads the entire party but will become my Prime Minister. Prime Minister of a government that affects my daily life, makes laws - wants to tell me what I can say, makes policies that affect where it is safe for me to go, taxes me, spends my money etc. I stick to my ideals, it would be illogical and doing myself a disservice as a intelligent human being to stick with one party no matter who is leading them. Their leadership can mutate the ideology throughout the party, into government and every single thing they do to me.
I could never, ever vote Conservative because I'm not a selfish, uncaring bigot.
Awful, just awful.
