You see, this is the problem with strategic voting. If the Conservatives cheat, you vote Liberal, and if the Liberals cheat, you vote Conservative. Many are like you, and the Liberals and conservatives aren't stupid. They know that as long as people vote strategically, all they have to do is wait awhile before the pendulum swings their way again, no sweat off their backs. What we have to do is stop voting for the party and start voting for the candidate. If we do that, then we're making things less certain for all parties, keeping them on their toes. After all, if a candidate knows that you voted for him based on his personal character, then he'll know that if he wants your vote come next election, he'd better vote on his principles and not along party lines. Once that happens, party strength diminishes. In addition to this, if you're voting for the candidate rather than the party, then even an independent candidate stands a chance. At that point, the party system collapses and MP's have no more choice but to all stay on their toes.
But as long as we keep voting in a Liberal/Conservative seesaw fashion, they'll just keep laughing in our faces... and rightly so. We deserve it. We get the government we deserve.
Ideally you would be correct. However it does not take into account the majority of people that don't bother to educate themselves at election time, or that vote partisan-ly every election.
The fact is that "party politics" has corrupted the system the entire way through. Our system is so flawed at the moment, that short of revolution, I don't see what else I can do to register my digust with the PM.
