Just some food for thought.

Someone should make a 1991 Europe map to compare. Spain and France were Left wing but the UK, Portugal, Italy and Germany were right wing. Those are the ones I remember, but I'm guessing that most of the countries in Europe were right wing at the time (the elected governments, since ex soviet-sphere countries that hadn't had free elections and were probably communist or something shouldn't count).

Yes, I know this has little to do with the topic at hand of change of governing parties in Europe, but just for contrast I made this

Blue is right wing, red is left wing.



South America 2000




South America 2011




I didn't color Suriname and Guyana because I have no idea what kind of governments they had and I'm too lazy to do the research. They are unimportant however

Yes, I know it's difficult to pin down a real ideology on a lot of these countries and some of them are hybrids or simple populists, but whatever, it's close enough
