There definitely is overlap between them and those who believe in conspiracy theories. But there are a lot of average people who vote for them as well. Like, middle aged, not particularly poor or wealthy. Your typical boomer...

Many AFD voters I've heard talking or saw what they write believe that specifically Muslim immigrants are bad for Europe. And/or they think that the green party is responsible for them having less money.

For those AFD voters who are immigrants, they vote for them because they believe refugees specifically cost too much money and they are also against the green party. At least, that's what I hear from the people in my neighborhood, which is mostly people whose families migrated from Turkey, sometimes two generations ago.

A third group think they somehow get back at the "elite" when they vote for AFD. Like a poor example of an act of defiance.

I believe that at least those who are not primarily xenophobic are still people we could bring to the other side. We waited to long to ban the AFD. I fear if they ban them now, the next right wing party will get a headstart in voters...
