Tesla sales plunged by more than half last month in several European countries in a sign that Elon Musk could struggle to revive the company after he shifts from his Washington cost-cutting work to day-to-day operations again. The countries are not major drivers of sales overall, but they are the first to report April results and thus a foretaste of possible trouble elsewhere as Tesla reels from protests and boycotts over Musk wading into politics. Financial analysts covering Tesla are worried about the Musk backlash but caution it’s not clear exactly how much to blame politics for the hit.
