It was a relief to see Melania Trump at the St. Louis debate.

I was worried that the svelte Slovenian had gone into witness protection. Or that she was cloistered at a spa in the Swiss Alps.

Melania virtually disappeared after her Republican convention mishap purloining some Michelle Obama speech chunks. And then, after the invidious 2005 videotape of her husband and Billy Bush surfaced — with the bros bantering about groping women at a time when Melania was pregnant — there was talk that she and Donald would do a Bill and Hillary “60 Minutes”-type interview where she stood by her Cheez Doodle.

It wasn’t her style, and that idea got dropped. Melania did issue a statement calling her husband’s comments “offensive” but saying that he had her support and suggesting that everyone “focus on the important issues facing our nation and the world.”

Who knew that the important issue would be a pussy bow?

On Sunday night, Melania swept into the hall, smiled and shook hands with her counterpart, Bill Clinton. It was a classy contrast from no handshake by Hillary and Donald at the start and the tacky tableau concocted by Donald Trump, who sat three of the women who have accused Bill of sexual assault in the front row, after debate officials rejected seating them in the Trump family box.
