to whatever extent American government (post carter) isn't fascist according to mussolinis definition lies some where in this part of the definition:
"After Socialism, Fascism combats the whole complex system of democratic ideology, and repudiates it, whether in its theoretical premises or in its practical application. Fascism denies that the majority, by the simple fact that it is a majority, can direct human society; it denies that numbers alone can govern by means of a periodical consultation, and it affirms the immutable, beneficial, and fruitful inequality of mankind, which can never be permanently leveled through the mere operation of a mechanical process such as universal suffrage.... "
given that much of american "democracy" is an illusion, at best whatever functions of democracy there are comes mostly through direct action of the population forcing their will on a reluctant government and is interfered with (well documented) through an institutionalised thought control apparartus... it's at least quasi-fascist....and if you consider corporate control of the state (U.S.) to be any different than state control of the (private owned) business sector (known examples of fascism) in their consequences.
