Politicians make lots of promises while running for office. But can they actually deliver? Most of the time, we don’t find out until after the election. But last weekend, as a first-time delegate to Colorado’s Republican state convention, I witnessed a major exception to the rule: Sometimes, you get to see promises broken in real time.

I’m talking about Donald Trump, of course, who has made some bold claims about his leadership skills during the presidential campaign. “We need a smart president; we need a great leader,” Trump says in a video clip on his website. “If I’m elected president, I will do a truly great job. I’ll make America great again. Everybody’s going to be happy.”
