This is exactly why I said in another thread that I would leave the country should he win the presidency (which thankfully I never have thought was beyond a long shot):
Call be a prune, square, old fashioned, but I still think our political process and specially a run for president should have certain standards. It is not a reality show to run this country specially in these times of war, debt, and recession.
This is exactly what I was expecting from Trump. I hope he still has most of his senses and he will announce he is not running, which is why he would do it on his show. I really would be shocked if he did, and I would really be worried for the country then.
