Good example. The CDU is in a coalition with the left wing parties and refuses to work with the AfD in any way, not even winning votes with their votes, on the basis that the AfD is right wing and thus inherently evil. So the CDU is indeed not a recognizably right wing party anymore, and has suffered mass defections for that very reason. If it were, it would enter into coalitions with other right wing parties rather than being taking orders from a partly literally called Die Linke.

> on the basis that the AfD is right wing and thus inherently evil

I thought it was on the basis of the whole Nazi thing. https://en.wikipedia.org/wiki/Alternative_for_Germany#Neo-Na... Everyone except Nazis agrees that Nazis are inherently evil.

The AfD has nothing in common with the Nazis.

"Nothing" is a strong word. I'd call it a lie but you probably already know it is.

If you deliberately ignore the well-sourced things in common from the above link, sure.

It's entirely possible to have a right-wing party that still takes the stance "we don't join coalitions with the Nazis".
