CASHMAN: IVANKA SHOULD GO IT ALONE.

Ivanka, it’s time to ditch your dad and protect your brand.

Your father’s take-no-prisoners campaign could be doing irrevocable damage to your $100 million fashion and lifestyle empire. You need to detach from the Trump Train.

The hashtag #GrabYourWallets is trending on Twitter encouraging women to stop shopping your line of clothing. You can no longer avoid the power of the purse now that your father’s 2005 “Access Hollywood” lewd hot mic comments have resulted in the boycott of your products and the stores that sell them.

Ivanka, you need to put your professional ambition above your dad’s political ambition and stay away from campaign rallies and interviews.

Digital strategist Shannon Coulter, responsible for the #GrabYourWallets hashtag, told the Guardian, “If Ivanka Trump had distanced herself from the campaign I would not be boycotting her. But something changed for me when that tape was released.”

Ivanka, you’ve tried to draw a distinction between supporting your father’s campaign but not serving as a surrogate. You told us last winter on Herald Radio that you have “no formal role” in the race.

You even called the Billy Bush leaked tape “clearly inappropriate and offensive.” As a 34-year-old mom of three, you even acknowledged your father’s language can be “uncomfortable for us.”

Last week at Fortune’s Most Powerful Women conference, you said, “I’ve always tried to maintain complete separation between (my brand) and the campaign.”

You can’t have it both ways. You can’t promote your empowering social media movement #WomenWhoWork while stumping for a man who’s heard on tape talking about being so famous he can grab a woman without consent.

Having you on the trail is the best strategy to help your father win in Nov. 8 — yet it’s a career curse for your clothing line.

You need to protect the company you’ve built and acknowledge your dad is losing by double digits in most polls. The race is all but over, but your career in the fashion world could have decades of success.

Your clothing line is geared toward the middleto upper-middle-class working woman — the exact demo that has rejected the wobbly GOP campaign.

My advice. Spend the next two weeks focusing on family and business — otherwise your dresses might not be welcome in ladies locker rooms either.
