Well first off, Trump is not a politician.
Second: Let him morph. I don't care. At least he's morphing into the correct political shape, anti illegal immigration, pro American in trade policies, building a wall on the southern border, etc.. I think it's better than the deceitful, treacherous behavior that the current Republican party leadership has morphed into. ( Ever wonder why they cave to Obama so easily? Another story in itself. Too long to tell here.)
That is a strange thing to say about someone advancing on his presidential campaign, a campaign that he has been trying to get off the ground since the 1990s.
As far as Obama, Hillary, Al Gore, and John Kerry, that was Trump's party during those years, and Bill Clinton is his favorite president.
Remember that Trump is the guy who wanted Charlie Rangel in his cabinet, McCain for his Secretary of defense, and he wanted Oprah Winfrey as his veep, both for 2000, and for 2015.
