As a businessman /entertainer he used politics in a way that facilitated and promoted his primary interests.
Now that politics has moved from low to very high on Trumps priority list, we are left to wonder who he really is, and try to cobble together his actual political belief system, using fragments of past statements and actions that come from a different context.
This lends itself to a range of wild speculation that typically coalesces around our own hopes biases and prejudices and may or may not represent the reality of who Trump is as a political animal.
I am predisposed to believe that Trump would be a huge benefit for the country. His loyalty would not be to any one party, repub or dem, but to his vision of what America represents. I look at the Trump ink blot and see traditional American values such as patriotism, free markets, family and an intolerance of politically correct progressive facism.
IOW, projection.
