What do you mean by corporatism? Do you mean it in Mussolini's sense?
There are substantive parts to Trump's campaign?
I know I'm being snarky, but literally the only campaign position he has published[0] is his "plan" for immigration reform.
However I'd argue that a stable, two-party corporatist government is essentially the same as a one party government.
Note that Hillary and Trump and Jeb are running pretty much the identical platform when you consider the substantive parts.
