Why didn't the Liberals Think of this?

This spring, Rick Mercer will host a star search for Canada's next top leader. 18 to 25 year olds are urged to submit a 3 to 5 minute videotaped speech (to the CBC rather than YouTube) with their 'prime ministerial message'.

...featuring a judging panel composed of former prime ministers Brian Mulroney, John Turner, Kim Campbell and Joe Clark, the CBC announced Wednesday.
The Next Great Prime Minister, set to air in the spring, pits five young Canadians in a question period with Canada's former leaders on how they would make Canada a better, stronger nation, with a winner chosen at the end of the show.

The article on the CBC's web site neglects to mention that while people identifying themselves with the Green Party will be allowed as candidates, they will not be invited to debate with representatives of the other parties.
