TORONTO What will be the legacy of Donald Trump, who has had a remarkable knack for defying predictions, smashing expectations, surviving scandal, misdeeds and incompetence, and achieving what seemed impossible? Heâs been impeached twice and blamed by many, including those inside his party, for an unprecedented violent insurrection at Capitol Hill. Then thereâs his handling of a pandemic that he minimized and politicized as it ravaged the United States, killing close to 398,000 people as of Monday. âI donât think there is much doubt he will go down in history as the worst president ever for how heâs undermined democracy and his failure in COVID-19 response,â said McGill University political science professor Daniel Beland.
