Polarization of Political Groups In Switzerland

On Sunday the right-wing People's Party in Switzerland won 55 out of 200 seats in the House of Representatives, with the Social Democrats winning just 52. What is more interesting is that the Centre-right party, presumably more moderate in its position, suffered heavy losses. After the electoral success, the People's Party is now demanding a cabinet seat for its "hardline" leader, Christopher Blocher. Some of you seem to think this is a great sign for the "right" in Switzerland but don't gloss over the fact that the greens also gained. Maybe this is a sign of the radical polarization of politics and the rejection of moderate political parties supporting the established government?
