AfD is in the awkward position of having now a mix of outright white supremacists, disgruntled socalists, conservatives and anything in between who are (understandingly) upset with current government in Germany.
That hodgepodge of opinions and values is kind of a novelty in german political landscape. The only unifiyng thing that I could recount for the current AfD is that they are upset of german current governance.
The pact they have made is fragile and lose, any party internal conflict can be quite fatal for them.
This gives a huge opportunity for foreign state actors be it China, Usa, Russia to consilidate a dominant block inside the party which when their inevitiable election success in autunm 2024 arrives will ensure that the foreign state actor who manipulated the AfD the best will have a extremely powerful tool inside the germany and thus europe.
Sadly US State Department has done a better job in manipulating than Zhongnanhai in recent years so I am not optimistic about the pro-China block of AfD winning the power struggle, they even may get purged.
Russia is preoccupied with holding themselves together, so it will boil down to a Sino-Us dualism again.
