There are several different groups supporting him for different reasons. The biggest, I'd argue, is the slightly right very populist. They're not into fascism per se, they just want a wrecking ball like Trump to go in and break apart the elite institutions they blame for all the problems and see no other way of influencing. There certainly are supporters who are encroaching on fascism territory. Then there's long time Republicans who have flipped on a bunch of issues to try to get support from these people Trump activated.
