AfD holds multiple municipal seats and Hitler never won an election (he got about 36.7% in 1932). The Nazis took over because liberals (specifically Hindenburg and co) appointed Hitler and then Hitler was able to take over when Hindenburg died in part thanks to paramilitary support. Just worth noting for gauging AfD's distance from potential takeover.

I highly doubt that the PRC wants them in charge or wants to help them get there, though.
