I'm not sure I fully understood your point, but about the question "how fascism if elected?": the Nazi Party won (i.e., it was the most voted party) in multiple elections in the late 20s/early 30s.
I was asking how an (elected fascist) government can be corporatist, if they are fighting a corporation. Doesn't a corporatist government fight for the corporations? From the answers I see, this government is partially corporatist. They'll fight smaller corporations if the latter don't fall in line.
