Some things have changed since Mulroney's tenure as Canadian Prime Minister. He is apparently no longer hopped up on Nyquil - while he's still smarmy, he no longer has the careful enunciation and telltale slur of one slightly drunk.
But the slimey lies are still there. He just decried his opponents for getting upset with him for singing on stage with Ronald Reagan, saying that the "loopy left" was crazy to criticize - totally ignoring the fact that we weren't objecting to the song, we were objecting to his sucking up to the American right and acting against Canadian interests.
He argued at some length that former Prime Minister Pierre Trudeau, whom he obviously hates, had no moral authority in Canada and had no right to be a leader. He implied that Trudeau was anti-Semitic and even pro-Nazi.
The character assassination continues with Lucien Bouchard, and since I'm no fan of Bouchard I don't care to dredge up the details, but I don't believe a thing Mulroney says. He's a bald-faced liar, a prime-time sleeze. His legacy is that he did such an execrable job as Prime Minister that he destroyed his party.
And as to his own moral authority, I think Stevie Cameron settled that question in her book On the Take.
