"I must say that the results of the last three days has been particularly pleasing. Sadiq re-elected as London Mayor in spite of a nasty, ad-hominem, negative campaign against him."

I admit I was not in London, but I saw no ad hominem attacks on Sadiq Khan. I saw attacks on his 'principles', but no attacks based on him as a human being.

I would be interested to see examples of 'ad hominem' attacks.
