I think it was because big corporations saw Trump as dangerous to the economy. Clinton was a safe choice. Trump, well, he would start a trade war. He said he might default on the national debt. He would deport 11 million illegals, which would hurt business and also hurt the economy. It wasn't just big business, economists, experts, newspapers, they heard what Trump was saying and they did not like it one bit. I think it is telling that Trump got the most support from the poorly educated, that he even said "I love the poorly educated." He was clearly unfit for office and dangerous. Clinton was fit to serve and a steady hand.
Fully Agreed. Any sane man would oppose Trump. Now if it was Kasich vs Hillary or Jeb vs Hillary then I think it will be very even - How can you blame then for not supporting a mad man.
Big Business is significantly to the right on all economic issues but there is a sharp diversion on social issues. Abortion ban is a strict no. Tim Cook is a gay CEO, how can he support these radicals even if he likes some economic policies?
Social Conservatism is essentially turning the executives in business off on a personal level along with immigration opposition (opposition to free trade) etc.
Also most of the exe are sane people, they understand science & all. You can't call Climate Change a hoax when the human habitation is under stake. How can educated people support this non-sense?
Kasich would have got good support.
