Nope, it's the entire party. Focusing on one person is simpleton and raw raw go sports team stuff. He certainly is a symbol, but an entire party he does not make. Eliminating the senators, aides, the MP's and the party's combined forces leads to misguided opinions and fanfare. For example, the loss of Hugh Segal is a bit hit to the Conservative party imo, but no one talks about that.
I still can't figure out why the Liberals didn't choose the astronaut as their leader.
