Donald trump started his run for office with an easy $1.8 million of his own money for jump starting his campaign. He spent $500,000 alone on hats and other apparel. Suffice to say he isn't afraid to spend his own money but as his campaigning continued the spending of his own money decreased. He saw that he was doing very well in the polls and Trump said it was a good business decision to simply spending less than he needs to.
He very recently posted on twitter that his campaign is $35 million under budget and than took a stab at Jeb Bush's campaign wealth. He has also said that he will start to run some very expensive advertisements costing him a lot of money out of his pocket. Donald Trump knows an easy way into the White House is buying your ticket and if he has to he plans to do just that.
My campaign for president is $35,000,000 under budget, I have spent very little (and am in 1st place).Now I will spend big in Iowa/N.H./S.C.
