I certainly agree that it's very questionable to have an explicitly regional party in the federal debates, but for clarity's sake, the criteria are 2/3 of the following:
-
having at least one sitting MP who's been elected as a member of that party
-
having at least four per cent national support in opinion polls
-
running candidates in at least 90 per cent of all ridings
After pulling the candidates, the Green Party only meets one of these criteria (the first).
Certainly, and I've already expressed how I feel about that. But I get it - they're able to leverage the electoral system to their advantage, and have in fact been the Official Opposition at times.
