Donald J. Trump says he wishes his daughter Ivanka and Chelsea Clinton weren’t such good friends.

That churning in my gut tells me he might get his wish before this presidential campaign ends.

Trump, the Republican presidential nominee, says he plans to “take gloves off” as he campaigns against Democratic nominee Hillary Rodham Clinton.

Big surprise, eh? Hardly.

But what about Ivanka and Chelsea? And their husbands, for that matter? The in-laws of the two nominees happen to be friends, too.

I’ve thought this might become one of the more interesting back stories of this campaign as Mom and Dad battle it out to see who voters will elect to become the next president of the United States of America.

I don’t know too much about Ivanka Trump, other than what I’ve read recently about her, that she’s an intelligent and engaging young woman.

As for Chelsea, well, we’ve all sort of watched her grow up before our eyes. She, too, is intelligent and engaging.

My curiosity, though, might be drawn to whether she’s able to compartmentalize her relationships the way her parents so famously have been able to do.

Bill Clinton got impeached by the House and was put on trial in the Senate, which acquitted him of the charges brought by House members. He was able to continue working through the rest of his presidency with the very men and women who voted to impeach and to convict him.

Hillary Clinton then ran for the Senate in 2000, promising to reach across the aisle to work with Republicans who wanted her husband kicked out of office. Who became one of her best friends in the Senate? Republican John McCain, who was among those who voted to convict the president.

Did their daughter inherit that ability to put the nastiness aside to preserve her friendship with the daughter of a famously crass politician who’s shown quite an ability to say just about anything to and about his political foes?

We’re about to find out.
