Hi Njall, welcome to the forum!
If you are prepared to go as far left as to vote Linke in Germany and Syriza in Greece you would likely vote Red-Green Alliance in Denmark, its a bit less radical than those two.
Anyway, why Liberal in PEI? Dont they have an NDP? What about Manitoba, would you also vote NDP there?
Hi politicus, thanks, and my apologies for my slight lateness in getting back to you, for some reason I didn't see this yesterday.
Anyways, with regard to your question about the Danish parties, it's likely that my view of the Danish political system would differ if I lived there and was eligible to vote, but for the purposes of this list I had to rely on what I had read about it. While I knew that I would position myself to the left of the Social Democrats, I had quite a little debate inside my head as to whether the Socialist People's Party or the Red-Green Alliance would be a better fit. Somewhat like what batmacumba said, I found that the SPP had their roots as a democratic socialist party. And while I broadly define myself as a leftist, democratic socialism has a bit more of an appeal compared to communism (although I am certainly receptive to communist ideals and principles), so I ended up putting the SPP down here. That said, I would definitely have a tough choice between the SPP and Enhnedslisten during the next election.
As for the Canadian questions, I put Liberal for PEI because, as DC Al Fine said, the NDP doesn't really exist in PEI, having received only about 3% of the vote in the last election. This leaves the Liberals and the PC's, and the former is certainly the more appealing option of the two. In Manitoba, yes, I would vote NDP. The province just sort of slipped my mind when I was making the list
With Canadian politics in general, I'm drawn to the most left-most of the viable parties. So federally, and in most provinces, that means the NDP, although that could vary depending on which riding I would be residing in. For instance, as I stated above, I am a member of the board of directors for my local Alberta PC riding association, a position that I took up after getting involved with the local PC's during the last election. As you probably know, in most of Alberta outside of Edmonton and certain parts of central and northeast Calgary, the NDP's and the Liberals really don't stand a chance at the present time. So that left me with a choice between the (relatively) moderate PC's, or the untrustworthy, opportunistic, right-wing Wildrose Party.
So, from the point of view I've read from Njall, his options make lots of sense. Except for the US Greens 
. I put the Greens, in part, as a sort of idealistic hope for the eventual erosion of the two-party system in the US
Of course, if I were to move back to the States, chances are that I'd vote as the true-blue, Seattle-born Democrat that I am.
