Can individual seats defect? Or does it have to be entire parties?
Yep. Quite likely to cause that person to be kicked out of their party though if they think it's severe/often enough. They keep it for the entire 4 years though. Seeing how infected the debate has been since the parties started campaigns, it feels unlikely that any from the Red-Green alliance is going to defect. I imagine that as soon as people have gotten the sand out of their coochies and stopped screaming, some backroom deals might be made between the Alliance and the Sweden Democrats. Me having voted for the Alliance, I'd have no problem with it. I would have a problem with them going together with any of the leftist bastards, and that especially applies to the Left Party (closeted communists the whole bunch), and the Green Party, AKA The Green Khmers by some here, for good reason.
