Trump’s most conservative trait is his ability to distinguish things that are important from things that are not. Would that many here shared that trait.
Conservatism is not wholly defined by one’s willingness to pander on social issues. Defining it that way got us Hastert, Livingstone, and Gingrich - three reasons why, when tried in the court of public opinion, Bill Clinton got away with it. Because his holier-than-thou persecutors turned out to be not so holy after all.
I would suspect that if you got him drunk (I know, he’s a teetotaler) and really delved into the man’s beliefs he’s probably one of the last of that near extinct breed we used to call a Sam Nunn Democrat. Patriotic to the core but Liberal on social issues. He, or someone like Sen. Nunn, could never be nominated by today’s Out From Under the Bed Red Democratic Party. But a coalition of frustrated Republicans and disenfranchised patriotic Democrats might just be a winning coalition. But at some point he will need to start sounding less like a TV reality shock show host and more like a president.
