For as long as I was old enough to think about politics, I have been a Republican. When my dad told me, aged six, that Bill Clinton had beaten Bob Dole, I’m told I cried. I don’t remember this, but do have vivid memories of running around St Andrews in my first year at university in a handmade McCain-Palin T-shirt with ‘NO-bama’ sketched in sharpie on the back.
