Well, after this, I think I need to do one of these:
Spain: IU if in Castilla. Any regional leftist otherwise. (is equo a national party?)
Well, there is more than Castile in what's the rest of Spain (I mean, outside our 'historical nationalities': Catalonia, Basque Country and Galicia). I guess that Equo is a 'national' party, though it didn't run lists in Catalonia because Iniciativa per Catalunya-Verds is its 'sister' party, member of the European Greens. In the Valencian region (País Valencià or Comunidad Valenciana) they made a coalition with Compromís (a mix Valencian nationalists, former IU members and greenies) and in the German colony known as Balearic Islands with the Partit Socialista de Mallorca-Entesa Nacionalista. Also Equo went with some small local parties in the Western Canaries.
My two cents:
USA: Democrat by default.
England: Labour for the same reason, as well in Wales and Scotland.
Northern Ireland: Though choice. Maybe the moderate hero option: the SDLP or even the Alliance, or even a pure and beautiful blank ballot.
Ireland: Labour?
Germany: The Greens, especially in Kreuzberg-Friedrichsain-Prenzlauer Berg East. In Hamburg probably SPD for state elections and in Baden-Württenberg I really don't know. In Austria Greens too.
Israel: Meretz or Hadash if I feel angry enough.
Canada: NDP by default. Blank ballot in Quebec provincial elections.
Australia: Greens first preference, Labor second.
New Zealand: Greens for the national list and probably Labour in a constituency.
Denmark: Between SPP and Red-Greens. Norway: Labour. Iceland: probably the Left Greens. Probably Greens in Sweden and Finland too.
Italy: The Vendola thing.
Russia: Anna Politskovskaya. No choice there.
France: European Greens by default.
Portugal: PS or Bloco de Esquerda if I feel angry.
Greece: Though choice between DIMAR, SYRIZA and a suitcase.
Belgium: Between Socialists and Greens in Flanders and Wallonia.
Mexico: PRD I guess.
Brazil: PT by default, in state and local elections depending on candidates.
Argentina: Broad Progressive Front?
Chile: Bachelet.
