The puzzling thing to outsiders is that most time politicians manage to present themselves in a superficially appealing way. You might not like them yourselves, but with a bit of imagination you can see how other people might. Not necessarily personally likable sometimes, but impressive.

But Trump, you'd run screaming down the street if you met him. He's so obviously a wrong 'un. The old question people ask of politicians is "would you buy a used car off this man?" Forget the politics - would any sane person buy a used car from Donald Trump?
