Donald Trump flew into the Iowa State Fair this weekend aboard his fancy helicopter.

He regaled the crowds and then gave children gathered around him free rides aboard the bird.

My wife wondered: “That’s all fine. It’s nice that Trump did that. My question is this — how many free rides to kids did he give before he became a candidate for president?”

Hey, maybe he’s the most generous billionaire real-estate mogul/reality TV star who’s ever lived. Or … maybe he’ a Scrooge.

My wife poses an interesting question that speaks to a larger issue.

You measure someone’s character by what he does when no one’s looking.
