You know, if the Conservatives were willing to make STV as a priority, well, I still wouldn't vote conservative under Harper, but could consider voting Conservative in future. But a Conservative majority? Oh boy. Start spit-shining the boots.
Actually, that's one (though not the only) reason I don't vote conservative. With a first-past-the-post system, it's just too easy for them to get a majority.
Harper aside, a Conservative-Green coallition would be a good mix in my opinion. The Greens would be pushing for Green-shifting, the Conservatives for tax cuts. That could be a nice combination (slightly higher gas tax, but income splitting allowing for a tax break. If the tax increase on gas is less than the tax cut on income, both sides might be happy. In fact, the Greens have generally been more in favour of incomse splitting than the Conservatives, ironically enough). Overall, the Conservatives would be trying to put the brakes on spending, the Greens trying to increase spending (I'm not contradicting myself here from the previous post; compared to the Conservatives, the Greens are still spenders. It's only compared to the other parties that they are economically a little more Conservative.) Afghanistan would be a big question mark though; the Conservatives want out by 2011, the Greens want to stay with no time frame but just change it from NATO led to UN-led.
Problem is, I doubt the Greens would want to associate with the Conservatives, but I could still see the conservatives wanting to associate with the Greens over the Libs or NDP owing to its economic conservatism.
