According to a report in Politico, Ed Stack, Dick’s Sporting Good’s CEO, is “quietly” testing a presidential bid as a third-party candidate.

The report said Stack has tested various messages with a focus group in Wisconsin. Focus group participants were asked to compare Stack in three-way races against President Trump and either of the two 2020 Democratic frontrunners, former Vice President Joe Biden or Sen. Elizabeth Warren.

Messaging in the focus group reportedly focused on Stack’s “leadership” after he said Dick’s destroyed more than $5 million worth of guns when his company made the decision to no longer sell assault-style rifles following the mass shooting at Marjory Stoneman Douglas High School in Parkland, FL.

A source close to Stack  downplayed his interest in a presidential bid, telling Politico: “Mr. Stack enjoys running Dick’s Sporting Goods and has no plans to run for any elected office.”

Stack in recent weeks has made several speaking appearances in support of his new book, titled “It’s How We Play the Game.” The billionaire has donated thousands to Republicans in the past.
