Clinton, Trump on grandparent watch
Likewise, Democratic challenger Hillary Clinton is not only enjoying her own primary wins but is also on grandchild watch later this summer. Her only daughter, Chelsea, 36, is also expecting her second child with husband Mark Mezvinsky. She has made several primary appearances sporting her own smallish and growing baby bump.
At eight months pregnant, Ivanka, 34, has been a popular Trump draw, joining brothers Donald Jr., Eric and their wives on the campaign trail. The head of her own lifestyle brand, Ivanka Trump cuts a fashionable and maternity-chic swath, speaking to rapt crowds and recording several campaign videos touting not only her famously brash dad's business credentials, but praising his softer side as a good dad.
"Donald Trump's kids are so well-spoken, polished and professional that they not only make their dad look good but they could probably teach him a thing or two about class and manners," says Dorothy Cascerceri, a New York City-based celebrity expert and TV host.
"Seeing a candidate's kids on the campaign trail humanizes them, especially when their kids are so impressive. There's a correlation between well-spoken, put-together kids and good parenting and they are nothing but a positive reflection on Trump," she added. "The same goes for Chelsea Clinton. Her involvement in her mom's campaign only helps Hillary."
Jane Sanders, who has been married to Democratic primary challenger Bernie Sanders for 27 years and is his second wife, has stepped up publicly to dismiss why her husband isn't too old to run for president at 74. Although less known perhaps than Trump's wife, Melania, Jane Sanders also charmed when she revealed Bernie's first pick-up line in an interview with Chicago's WGN radio.
She shared that they first met when she was a community organizer and was working on a mayoral race. And it was he who made the first move, flirting just a bit.
"He actually did. He and I met eyes during that debate. He impressed me. It was his idea, of course," she said of their first date. "His first pick-up line to me? 'Have you had dinner?'"
As innocent as their start as a couple, thus far, other political families have offered little scandalous fodder during the 2016 campaign, appearing perhaps less colorful than previous presidential siblings who garnered headlines.
"The general rule when it comes to campaign families is 'first, do no harm,' " says conservative pundit and author Lisa De Pasquale. "Past campaigns have had colorful characters, like Billy Carter and Roger Clinton, but you can't say they were a liability since both of their brothers were victorious."
"In 2016, the children of candidates are likely to garner attention for the cute factor as with Cruz (and daughters Caroline and Catherine, 7 and 5 ) and Rubio (with four children, two girls and two boys, ages 15 to 7) and success factor (Trump)," she adds.
Chelsea Clinton, at least in De Pasquale's view, is less of an asset than what Simone suggests. She believes Clinton comes off as "privileged."
"She is different from the Trump kids because, despite growing up in privilege, they have actually been involved in day-to-day business," De Pasquale said. "Chelsea has benefited from her parents' connections as tag-along for overpaid speeches and a lucrative NBC contract with little on-screen work to show for it."
Still, De Pasquale says, families in the best sense often pull back the curtain on a candidate's private life and allow prospective voters a new view and unscripted moments. Such sharing must be balanced.
"It certainly says a lot about politicians," she said, "when so much of the conversation is focused on how to humanize them."
