The May elections are absolutely critical, and I think people are downplaying the potential threat. The estimates are that they'll gain 170 or so seats of a parliament that has over 500 members. Some say that's not a big deal, but I think it is a big deal. The parliament as it has existed to date in the European Union is dominated by the EPP, the centre-right group, and there's a very real possibility that as these groups get organized in the ways that Professor Williams described, the EU could become dysfunctional.
I think the European Union is not a democracy; its member states are, but the fear that I would have about these parties is that they dismantle the European Union. If they do that, it does undermine democracy within nation-states. The thing to focus on is the degree of Euroscepticism that these parties often offer.
