A new Harris Poll backs Trump’s critique of the NBA, with 39% of sports fans saying they are watching fewer games. And the chief reason why? Politics. The longtime polling agency surveyed nearly 2,000 people over the weekend and gave those who identified as sports fans—two-thirds of the total—ten options to choose from on why they are watching less basketball.

“The league has become too political” was the clear choice, with 38% of respondents who identified themselves as sports fans. “Boring without fans” captured 28% of the vote while the NBA’s association with China caused 19% of sports fans to turn the dial, another nod to a league Trump labeled a “political organization” last week after players boycotted games in response to a police officer shooting Jacob Blake seven times in the back in Kenosha, Wisconsin.

While 39% of sports fans say they are watching fewer games, 32% answered they are consuming more basketball this summer (28% say the same amount). Harris did not ask those fans why they were watching more.

NBA ratings are in fact down overall through the first round of the playoffs compared with last year, but it’s hardly an apples-to-apples comparison. Summer TV viewership typically lags springtime watching, when the playoffs are normally aired. This year, the overall numbers are skewed by the need to air games during the day to accommodate a playoff calendar that has been condensed because of the pandemic. Ratings are up over last year’s playoffs for the games that have aired in prime time.

“While the data shows the league’s political leanings will undoubtedly cause some not to watch, the NBA is balancing the issue of racial injustice, supporting its players and completing a successful finish to the season,” says John Gerzema, the Harris Poll CEO. “The basketball bubble has kept the league immune from cases of (COVID) infection but not immune from the impact politics can have on ratings and public sentiment.”

Trump and the NBA’s star players have been at odds since he took office in 2017. It’s a tradition for teams that win championships to visit the White House, but the Golden State Warriors, who won the 2017 NBA Finals, followed the lead of their star Stephen Curry and refused to visit. Trump quickly withdrew the invitation after the slight. LeBron James has called Trump a “bum,” and Trump targeted James after the four-time MVP appeared on CNN discussing the opening of his charter school.
