Former NDP MP Lori Idlout joins the Liberals, letting them secure a majority if they win two of three April byelections. NDP president Mary Shortall and leadership candidate Heather McPherson react. Former Liberal Party campaign co-chair David Herle, former NDP director Anne McGrath and former Conservative chief of staff David McLaughlin debate the pains it could cause each party — including an even smaller NDP caucus, a Conservative Party drifting further from power and the difficulty of managing a 'razor-thin' Liberal vote advantage in the House. Plus, Nunavut Premier John Main discusses what he hopes the crossing of the territory's only MP will mean for its future.
