Why focus on those, why not read those who respond directly to those questions you raise?
The one about donations has been answered directly by Trump himself dozens of times at his rallies and in interviews, and hundreds of times by supporters like myself right here on FR.
Those answers say that Trump opposes his own party and supports the Democrat instead roughly 25% based on the numbers I accept from Trump supporters themselves.
I still have not heard a good reason for doing that. The excuse about big successful companies have to play the game is easily refuted. The Koch brothers are a well known example.
And other candidate that had financially supported Democrats 25% of the time would be called a RINO by Trump supporters themselves I bet. Why the pass for Trump?
