The fact that the PAC donated to Pramila Jayapal shows that clearly supporting fascism isn't the point of the donations. But I would absolutely say that each of Ted Cruz, Josh Hawley, and Lindsey Graham are (were in the Graham's case) fascistic in their positions. All of them support(ed) Trump, who readily accepted a description of "fascist" from Mamdani, on camera (if his status as such weren't already self-evident).
