Carson has done much less than Hillary so he has less that needs to be spun. In absolute numbers Hillary is far ahead, percentage-wise, not so much.
All you sources are on a planned meeting that never seems to have taken place. What he said was: “I got to know him very well because we were both on ’60 Minutes,’ we were stablemates, and we did very well that night” The two did appear on the same “60 Minutes” episode, which aired on Sept. 27. But journalist Charlie Rose
traveled to Moscow for the two-hour interview with Putin, and Trump was interviewed by Scott Pelley in Trump’s
Fifth Avenue penthouse in Manhattan.
Trump vs. Fiorina: Who Knows Putin Best?
They are all politicians. I put Trump in the same category: he's running for political office so caveat emptor. Personally I never believe what one says about another. I don't even care much what they've done in the past. I only care about what they'll do in the future should they win. What Hillary proposes is closest to what I'd like to see. I have no clue what Trump will do, only that he can't do what he has promised.
