Circa 1988 - 89, Donald Trump, the Jersey Casino guy, pitched his doomed Taj Mahal Casino deal to the Merrill Lynch Bond Department to launch the ML-underwriting.
He was full of himself, every other word (I exaggerate a little, lol) praised his deal, the future of Atlantic City as a Casino Destination Resort, and himself.
I recall being totally turned off but--to be fair--it seemed a common trait among corporate CEOs and Big Time Investment Bankers,back in the day. Gordon Gekko wannebes I suppose.
And to be fair one mo' time, 'selling one's charisma' charmed buy side clients most of the time on road shows, before the harsh reality of making good on 14% debt proved futile in many cases.
