Who would you vote for?

[Middle-aged Europe]

Germany - Greens or SPD

Spain - PSOE, possibly also some of the regional parties as long as they´re no hardcore separatists

Portugal - Partido Socialista

France - Parti Socialiste, PRG, or Les Vertes

Italy - basically most non-communist members of the Olive Tree alliance: Democratici di Sinistra, La Margherita etc.

Australia - ALP, Australian Democrats, or Australian Greens

Canada - Liberal Party or NDP

United Kingdom - Liberal Democrats or Labour

Ireland - probably Labour Party

If they have significant presence in the country's politics, I counted them. The UKIP did very well in the EU elections and will have an affect on the Westminster Elections and the FN holds a significant portion of the French Assembly.  Lega Nord is in the same boat as the FN.

The Front National doesn´t hold a single seat in the National Assembly at the moment. Granted, they received a relatively large percentage of the vote in the parliamentary as well as the presidential election, but no FN member currently holds an elected office on national level.

Germany: district vote SPD, Lander vote FDP

With "Lander vote" you mean the vote for the party list in national elections, yes?

That´s a fairly unusual combination nowadays since the FDP allies itself with the CDU most of the time. You should probably move to the state of Rhineland-Palatinate (last German state with a SPD/FDP coalition government).
