I thought that people on HN didn't resort to ad hominem when they're being so visibly sanctimonious.

I know that, in theory at least, people vote for the party, not the leader. The Blair-Brown transition wasn't unprecedented, but equally morally and ethically questionable. The difference here is that the Tories, who currently have a significant majority, are in complete disarray and are clinging to power that, if the latest polls are to be believed, would see them all but wiped out.
