Both Reagan and Trump were former Democrats and both of them were hated by many in the establishment Republican Party and also the liberal media. Unlike Richard Nixon, both Reagan and Trump knew how to handle the media and circumvent it to reach the American people directly.
And yet he is worshipped by Rush, Mark Levin, and many others.
If you expect to be President, you must live in the world of what's politically achievable at the moment.
If Trump should get the nod, he will never make lofty and poetic speeches like Reagan did. But that's not necessarily bad. Trump has his own way. He's a businessman staying true to himself. Trying to act the part of a "statesman", he would lose some of his credibility, I think.
More than anything, Trump is a strong and nurturing Dad. And if a Dad raises a good for a family, perhaps he would also be good for raising a nation.
