I have plenty of problems with the Clintons' financial behavior, as I wrote. But at least Hillary Clinton is proposing tax code changes that would cost her and her family money. Trump, by contrast, is proposing tax changes that would greatly benefit the commercial real estate business, which is his primary field, and would greatly benefit his own family. And when I asked his campaign last week whether he was proposing any tax changes that would cost him and/or his family any money, I got no reply.
