Woman whose MAGA hat meltdown, subway wipeout went viral is an ‘extremely liberal’ luxury-brand specialist

She’s going to need a re-brand!

The woman who received “instant karma” after berating a President Trump supporter on the subway — and then face-planting on the platform after trying to grab his “Make America Great Again” hat — is an increasingly “agitated” creative director for several luxury brands, The Post has learned.

Alberta Testanero, a 55-year-old dual Italian-American citizen, went viral for the caught-on-video incident on the 6 train in Midtown last week after branding the MAGA fan “uneducated” and a “racist.”

Testanero has gone off the deep end when it comes to politics, a former colleague claimed.

“She and I stopped being friends a while ago, as she became extremely liberal and very agitated,” the one-time coworker told The Post.

“I see nothing has changed, but now she’s gotten into the extreme, doing things like this,” the coworker said of the subway incident, adding that Testanero was known to argue with Republicans and frequently call out people she deemed “racist.”

A freelance creative director and branding specialist who has worked with posh outfits like Tiffany & Co., Coach, Bergdorf Goodman and Kate Spade, Testanero prides herself on “maintaining the highest standards,” according to her online profiles.

“An experienced team leader, I have a keen understanding of the relationship between corporate strategy and creative vision,” the Murray Hill resident and Fashion Institute of Technology alum boasts on her LinkedIn. “No matter how large or small, I approach every project with enthusiasm always furthering brand vision and maintaining the highest standards.”

On a Facebook account apparently belonging to Testanero, she shared a family photo of the Obamas and a bizarre image of “Joe” and “Barack” friendship bracelets.

The lefty art designer publicly called out the MAGA fan, wagging her finger in his face while aboard a northbound train around 11:30 p.m., according to a video that has since racked up more than 5 million views.

“If you f–king voted for Trump, you’re a racist!” Testanero yelled at the man during the March 19 incident.

The young man laughed, asking how he could be racist and arguing he is indeed “highly educated.”

“Oh, are you?” Testanero responded. “Then why are you wearing that hat? Only uneducated people wear that hat.”

Some bystanders urged Testanero to leave the guy alone. “That’s why he won, because of people like you,” a rider chimed in.

When the man got off the subway at the 28th Street station, Testanero lunged at and chased him, trying to grab the hat before she fell face-first onto the filthy floor.

Social media users slammed Testanero as the “perfect definition of the left.”

“This is a great example of brainwashing,” one Instagram user said. “A hat should not elicit a deeply emotional response. Step out of your echo chamber once in a while.”

Testanero did not respond to inquiries and refused comment when The Post showed up at her Madison Avenue apartment building Friday morning, telling the doorman to turn the journalists away.
