Yes, it's pretty terrible that Liberals are pulling this stunt. But to everyone mentioning Harper and complaining about "The Left" or fascism or whatever, the Conservatives did the exact same thing in 2009.

If you're a fan of one leader over the other, you have to reconcile how it's good for one to do shut down government but bad for the other.
It's more likely that politics is hard and these leaders are fallible humans who don't know how else to get their bills through.
