The final debate of the federal Liberal leadership race saw some sparks fly over the issue of fostering strategic voting.

The six leadership hopefuls covered topics ranging from the environment to getting youth involved in politics.

But the most lively exchange came up over word the Green Party isn't going to run a candidate in an upcoming Newfoundland byelection.  

Leadership hopeful Joyce Murray took on the perceived frontrunner Justin Trudeau over his disdain for cooperating with the other opposition parties to end vote-splitting.  

Trudeau said such flirtations will likely result in NDP leader Tom Mulcair becoming prime minister.  

But Murray countered that Canadians want a style of electoral system where their politicians are working together.

She says having just one progressive candidate on a ballot is a step toward achieving that.  

The other contenders in the race are former cabinet minister Martin Cauchon, Toronto lawyer Deborah Coyne and retired military officer Karen McCrimmon.  

The party will choose a new leader on April 14th.
