But all you are saying is that "mentally ill narcissist" is a more important issue than abortion. It might be, might not. Abortion isn't my issue.
If you mean to say there is no True Scotsman, I have to agree. But it is a handy category, and I have chatted with people who answer every charge against a candidate (I think it was Huckabee) with something like, "That may be so, but he's against abortion..."
To be honest, I rather like the Brit system where you vote for a party instead of a person (at least that's how I understand it). At least that way we could (hopefully) set aside personalities and focus on agendas. It sometimes seems to me we've confused selecting a president with selecting America's Top Model or something.
