They have plenty of guys in their fold with plenty of public personas to tap when the time is right. Trump definitely is an American Nationalist in the sense that he's a stalwart supporter of the system by which his masters place their invisible chains on the American people. Why does an American Nationalist allow the system to destroy American wealth under the guise of CV prevention when all it would take is for him to step up and tell the truth? Why does he keep packing his press sessions with people hostile to his supposedly America First agenda? He could have created a whole branch of conservative reporting media just by giving grass-roots journalists seats in press conferences and calling on them.The reason I believe Trump is actually an American Nationalist, at least of a sort, is that he's been saying the same things about trade for 40 years. He really did oppose the Iraq War on nationalist grounds. He's a Johnny come lately on immigration, but lets not forget that he has a long record of statements that fit with how he ran in 2016.
In truth we have to dig and dig and dig for excuses to maintain suspension of disbelief in his persona while simultaneously ignoring mountains of evidence of his treachery.
