The polarized political landscape is probably a result of the voting system though. In a winner take it all systems, you can get a vote at "any cost" since you won't have to make any coalition later. The only thing in favor of the system is that it creates a clear winner, proportional systems might be more fair, but if parties fail to create a majority coalition you are back to square one. An ideal system might need to mix these two approaches (and some other like vote ranking, lists, etc)
