Hey!
Don't look at me, I never voted for GW Harper!
But seriously - the main reason we have a Bushish federal government here is that the previous Liberals shot themselves in the foot (among other body parts) with stupid scandals.
Plus the fact that there are four parties that garner significant numbers of votes, thus splitting "the left" into small enough pieces that "the right" waltzes in.
But just wait until Justin Trudeau comes of age politically.
