Abstract: We briefly review the concept of scaling and how it occurs in quasielastic electron and neutrino scattering from nuclei, and then the particular approach to scaling in the short-time approximation. We show that, while two-nucleon currents do significantly enhance the transverse electromagnetic response, they do not spoil scaling, but in fact enhance it. We provide scaling results obtained in the short-time approximation that verify this claim. The enhanced scaling is not ``accidental'' -- as claimed in Ref.~\cite{Benhar:2020jye} -- but rather reflects the dominant role played by pion exchange interactions and currents in the quasielastic regime.
