It’s another debate night for the federal party leaders.

This time it’s the nationally televised French-language debate.

Political analyst Allan Warnke, a retired VIU prof, says English Canadians should take note of the debate as well, for several reasons.

In particular, the exchanges between the NDP’s Tom Mulcair and Justin Trudeau of the Liberals, who both have a lot at stake in Quebec.

This debate is the first time Mulcair, Trudeau, Conservative Stephen Harper, Green Elizabeth May and Bloc Quebecois leader Gilles Duceppe will share the stage.
