Anti-establishment-politician sentiment, certainly, but anti-politics? That depends on how you define politics.
My definition of “politics” is all about choice over policies: citizens in a democracy can choose to fundamentally change their country’s economic and social policies, if that is what they want to do. In 2011 Irish voters voted for change, and got none: the new government faithfully implemented the Troika programme, just as the previous government had done, and presumably would have continued to do had they been re-elected. (And now that they have been let off the leash they are coming up with bubble-era proposals to increase mortgage lending. Not much change there either. And consequently not much real choice.)
Democracy without choice is not democracy. Politics without choice is not politics.
A lot of people in this country, and right across Europe, want real change. Some in Ireland voted for Sinn Féin, the big winner in the election. Some voted Independent. This isn’t anti-politics. It’s anti-anti-politics.
