We have only won a reprieve with our victory last night. The house is still controlled by the anti gun Liberals, NDP, and BQ. They could get together and introduce private members bills on the subject just to embarass the conservatives when the time comes. To top it off, the "has been" Liberal appointees will control the senate for at least 5 more years as well, so don't count on too many reversals of these Liberal "victories".
There are two things now which will make the difference. First, with the conservatives in (minor) control of the house, they must start really investigating the adscam etc, whereas the Gomery commission really had a narrow scope of questions to look into. I suspect and hope that the Conservatives will start sending Liberal politicians along with the backroom boys to jail, and timing it with any future election. This worked great in Saskatchewan after the provincial Conservative Grant Devine era, after which the NDP continued to send conservatives to jail for graft and theft for the next 8 years. The Conservative party in Saskatchewan finally had to fold up. (They now exist as the Saskatchewan Party).
Second, Harper must now appear as a rational, thoughtful, and smart politician. It was only the Liberal fear mongering that kept the party down. Combined with the reaults in my first scenario, the conservatives could pull a majority in the next election.
I wouldn't bother putting the drill in the drill press to take out those rivets quite yet.
