In the mid-to-late 1960s, the NPD managed to retain a degree of decorum for some years before jumping the shark in the 1970s. Similarly, the Republicans started out as a CSU breakaway but quickly morphed into yet another extremist group in the eyes of the public. Later attempts of the new leadership to return to a more moderate position came too late to remedy the situation. More interesting was Judge Schill’s attempt to create a modern right-wing populist party in the early 2000s, but they never did well outside Hamburg and quickly collapsed due to Schill’s erratic behaviour.
The AfD leadership, on the other hand, has so far managed to keep well-known extremists out of the party (or at least out of the limelight). But recently, the party’s image has suffered two significant blows. A couple of weeks ago, the AfD in Brandenburg was forced to expel a newly minted state MP who had posted an antisemitic cartoon on Facebook, alongside a link to an extremist propaganda site. This week, it transpired that a party leader in the Eastern state of Mecklenburg-Vorpommern has been charged with inciting racial hatred over (anonymous) posts on the interwebs.
Whether this is actually true remains to be seen. Either way, both events in isolation will not hurt the party, which is doing very well in the polls. But they will help to strengthen the cordon sanitaire that Merkel has created between her own Christian Democrats and the AfD, and resonate with the extremism frame that the left is deploying against them.
