I found a random Bill Clinton temple reference in the wild in a Twitch/YouTube Mario Maker 2 streamer’s video.

Go to time 26:36.

It can be found in MM2 using the level code PKN-C64-X8G.

Level is called “Bill Clinton’s Crazy Busy Temple”

The streamer doesn’t get the reference, but the Koopa kingdom creatures are held captive in claws, and as Mario travels through the level he can free them.
