Once Liberal Netherlands Might Have Extreme-Rightist-Led Government?

Poll results indicate that Dutch anti-immigrant politician Geert Wilders might become the first explicitly right-extremist prime minister of an EU-member state (see here or here for more). Should that happen, the truly interesting question is how the European Union will react to the emergence of a government in one of its member states that pursues political goals that might clash not only with the EU's rules of behaviour, but also basic human rights. (In my humble opinion, probably nothing will happen, just as it did [not] in the Austrian case when the right-extremists were junior members of a coalition government.) What a mess.
