Ah, to be young and alive and Ivanka Trump in those heady summer days before the GOP convention. She was Trump’s secret weapon.  Exhibit A of his greatest success. “Look at my great kids! How big of an asshole can I be with a family like that?” said the nominee of the party of Lincoln, Eisenhower, and Reagan.

She runs the family business. She’ll be his White House Chief of Staff. Maybe she runs for Governor of New York. So smart . . . so strong . . . look at that dress . . .

And, yeah, it turns out she’s likely pretty smart, because she’s walked away from her father’s campaign faster than a Republican governor in a swing state.  We last saw her make a convention speech introducing her father. The speech focused on family leave and women in the work place and would have fit perfectly into the Democratic convention’s Wednesday night schedule.

Other than that, as far as I can tell, her only other major appearance was a cameo last month when her father announced his maternity leave plan. I know that no one cares about policy in this election, but it’s worth noting that Hillary has proposed a significant expansion of paid family leave.  For men and women. And not just for pregnancy, but to support people with seriously ill or dying family members.

Trump’s proposal only covered pregnancy.  And only applied to women. And wasn’t paid leave, but merely a tax deduction. For the populist blue-collar candidate, it was an old school rich-guy Republican proposal.  Not even a tax credit, which directly reduces a person’s taxes, but a tax deduction which only reduces the income being taxed.  And almost 70 percent of Americans don’t itemize their taxes; they take the standard deduction. But, really, who cares, because it’s likely that Trump forgot about the proposal five minutes after his daughter made him announce it.

Other than that, I haven’t seen her on Morning Joe or The View or appearing at voter registration rallies in Ohio or Women Entrepreneur conferences at the Wharton School.

Ivanka’s friend Chelsea Clinton is doing several appearances a week for her mother.  Her brothers, Eric and Don Jr. are out there, charming the American public in a way that only third-generation billionaire real estate developers can, scribbling in their pocket-sized Moleskin note books lists of people they are going to “sue the shit out of” when this thing is over.

None of this is meant to be a criticism of Ivanka.  One of the last remaining areas of bi-partisan decency is that a candidate’s family members who are either too young or not inclined to participate in politics are off limits. It’s one of the reasons why when nude photos of Melania Trump were published, the Democrats didn’t make an issue of it.

But Ivanka, pre-convention, was one of Trump’s most popular spokespeople. She was out there.  And then she just stopped. He’s getting killed in the polls with women in every age and socio-economic group. Wouldn’t a leering, groping, fat-shaming, “hey-honey-twirl-around-for-me-would-ya?” candidate benefit from his business woman daughter campaigning for him?

At the GOP convention, we were presented with Trump’s family as a reason—perhaps the only compelling one—to trust him with the presidency.  Since then, the Trump men have been prominent in support of their father, while his wife and daughters have demurred.

Maybe Ivanka is the smart, strong one in the family.  I wonder who she’s going to vote for in November?
