News from Spain where a far-right political party called Vox lost seats in the recent general election. Vox are culture warriors in the mould of the US MAGA movement: anti-migrant, anti-LGBT+, anti-Islam, anti-feminist and with a predilection for blocking action on EU climate goals. The response in Brussels to Vox's poor showing was triumphalism. But the uncomfortable truth is that Vox could well have been headed into power as the preferred coalition partner for Alberto Feijóo, the leader of the Spanish conservatives. As it turned out, the July 23 election was a stalemate. A coalition with Vox looks less likely, for now. But Vox could yet form part of a conservative-led government in future. And the prospect of conservatives relying on the far-right mirrors a similar dynamic across Europe. Conservatives already partner with the far-right in Italy, Sweden and Finland and at the regional level in Spain and Austria. Even the leader of Germany's conservative CDU has been eyeing such an arrangement. So how to make sense of this courtship of far-right parties? Can conservatives defang those to their right by co-opting them? Or does co-option merely give bigotry a bigger platform and move politics in a more radical direction? Whatever the case, conservatives bear a special responsibility when making alliances to their right. That special responsibility was the topic of our episode with Harvard professor Daniel Ziblatt a couple of years ago. We're re-running an abridged version of that conversation in response to what's happening in Spain — and because we're in the run up to EU election season. The European People’s Party, which groups together centre-right national parties, is flirting more openly than ever with potential allies who represent a new era of blood and soil politics, and who balk at modern progressive democracy — including the need to address climate change. Conservative parties "have to deal with and think about and worry about what happens on their right edges," says Dan. They must "figure out a strategy to distance themselves from these groups, but at the same time not allow these groups to get out of control, and shape politics."
