Buzzfeed has a story about how Donald Trump made a bunch of promises to win a bid to convert Washington’s Old Post Office to a hotel and then broke every one of them. As a businessman, Trump says and does whatever it takes to get the deal done. As a candidate, Trump says whatever it is he thinks people want to hear right then. As president, Trump won’t be negotiating deals to build hotels. He will be pledging “our lives, our Fortunes, and our Sacred honor” to other governments in a world with a very long memory for broken promises.
