The fallout from Elon Musk’s plunge into politics a year ago is still hammering his Tesla business as both sales and profits fell sharply again in the latest quarter.

Tesla has offered low-interest loans and other incentives to try to revive sales, but these efforts have depressed the company’s profits. Tesla’s newest model, the Cybertruck pickup, has been a flop. The company sold 4,300 Cybertrucks in the second quarter, according to Cox Automotive, a 50 percent decline from a year earlier.
