Sorry, the left was willing to compromise. NDP was willing to step back from its decade (or more) support for MMP.
Even if Mr. Trudeau doesn’t understand it (which I don’t believe for a minute) there are plenty of clever folk in his party who might explain it to him. It seems Mr. Trudeau is not interested in long term stability and collaboration. He much prefers the old fashioned kind of absolute power his father wielded back in the day. When Justin Trudeau threw his hat in the Liberal leadership race, his entire campaign was “I’m listening” on everything but electoral reform. He is simply not buying. Which is why we must insist.
