Twice during his tenure as mayor of NYC, Trump embarrassed Bloomberg. First when outbidding Bloomberg's consortium for the purchase of what would become the Hudson Yards, and afterwards Bloomberg personally thwarted Trump's development plans in concert with Jerry Nadler, and second with the reconstruction of the Prospect Park Carousel in Brooklyn. Nadler had earlier been refused by Trump for the usual political extortion baksheesh by Trump during another private development project in his district on the upper westside, starting their feud. Bloomberg stomped his little foot down, and refused Trump the rebuilding of the Forest Park Bandshell, arranging a no bid contract to his friend Andy Storms. Andy never did the job, ending up in prison for bribery, having bought city construction contracts from the Brooklyn and Queens democratic clubs. Bloomberg never forgave Trump for dropping a dime on Andy, even tho it was an FBI burn thanks to one of Meade Esposito's Court Street cohorts in Brooklyn the FBI picked up in a securities fraud, Max Hans a patsy for his former law practice partner, and flipped.
People should not forget, it was Bloomberg, after being refused the democratic candidacy for mayor, a lifelong democrat, Bloomberg entered the race as a Republican candidate. Setting the pattern for Trump, another lifelong democrat, to enter the presidential race as a Republican, another billionaire pissed off at the democratic machine.
