He belongs to the FDP, the German corruption party that will try to trick dumb first-time voters into voting for them, and then, when they eventually succeed every 3 or so election periods, implement maximally corrupt clientele policy for the ultra-rich, only to sit tight and wait out until the public forgets what they have done to rinse and repeat that very pattern. They have been doing this for decades.

This guy doing some cringeworthy TikTok video is no surprise, and since they are currently in the governing coalition, and on the usual downwards part of their popularity curve, which always happens when they do their thing, he is free to experiment with new ways to trick the next generation of first time-voters, as failure in doing so won’t really hurt the party anyway.
