I disagree very much, since that would mean that you would have to be an outright Fascist to be a radical right winger. I think that the neoconservatives surrounding Stephen Harper right now (not to mention down in the States) are profoundly radical, though they might not be Fascist.
Likewise, you suggest that fiscal prudence means that they cannot be left wing. I think that fiscal prudence can exist (and not exist) on both ends of the spectrum.
I think the electoral reform that might be coming should address this problem to an extent, as people will be able to vote for the Liberal candidate in their riding, if that's needed to fight off the Cons, and still give the party vote to NDP or the Greens. That'll certainly be a new option.
^It's exactly the same thing on the voting level. If anything, the party takes the proportional vote and decides what to do with it, you don't. Plus, there are fewer MPP positions to vote for in MMP. Local representation is being reduced is such a system.
As to the Liberals campaigning like the NDP but governing like the Conservatives, what does that actually mean?
liberals promise extensive social programs in the election campaigns.
When they govern, they see it is a major priority to be in a sound fiscal position, which is something you think the conservatives would worry about. They always want to be in surplus but they never go crazy with tax cuts.
Also, they usually wont go in debt ever even if the economy is good, unless there is an emergenacy.
The reason why the Mike Harris Conservatives went into so much debt is that they tried to give us tax cuts when they didn't even have enough money to fund all of the governments expenditures.
