Sorry, the other posters mentioned salary. Your complaint is that you feel Trump should not have lent money to his own campaign?
Your position makes little sense. I suppose you prefer Jeb Bush-style, bought-and-paid-for candidates.
My complaint is just what I said. Trump is being dishonest when he says he is funding his own campaign. He loans the campaign money, the campaign spends money, donors give money to the campaign, the campaign pays Trump back the loan. He is out nothing, it is all paid for by donations. IF he wins the nomination all pretense will be gone and he will be out begging for money like everyone else, and his supporters will say he is different because he won’t promise the big money people anything in return. It will be a lie, but they won’t care, as always.
It’s politics and Trump has been a player for a long time.
