Notice how the article subtly carries water for the liberals/fascists by only mentioning Bottoms (a liberal) as the opposition, while leaving out any progressive or leftist ones.
The effective opposition to the fascists would be somebody like Jason Esteves (of the candidates whose names I recognize, anyway), not Bottoms.
A shoe molding is thin enough that it could bend to follow the ceiling contour and wouldn't need to be scribed (which is the point of it). It would effectively hide the imprecision, but it would diminish the modernist aesthetic.
