the system is working perfectly, but Chris wants cataclysmic change with bare majorites (achieved by dubious means, but achieved nonetheless).
He points at the GOP rather than at his own party. But his party has gone too far overboard to keep unanimity, and they couldn't even come back to the center even slightly to strike a compromise.
If the Left does, this, then the GOP will (and should) play by their rules as they did with the Harry Reid Rule. Their rules, no mercy.
I suspect the Left thinks that if the get these voting changes, the GOP will never hold the WH with Senate again. This fairly much confirms that they know as well that this is about nonID laws that let them fix the elections permanently.
