In Tuesday's Globe and Mail, Michael Valpy writes that Jack Layton "was a modern 21st-century social democrat in a conservative era, who knew that the most effective response to his opponents was the politics of relentless optimism and sunny hope.
"It was a natural manifestation of a warm and gregarious personality, but also a demeanour he deliberately cultivated in his electoral and parliamentary confrontations with Stephen Harper's Conservatives. "
On Tuesday at 11:15 a.m. ET, Michael Valpy will join Globe readers to participate in a live discussion on the legacy of Jack Layton.
