Sales of Tesla electric cars fell sharply in the last three months as boycotts over Elon Musk’s political views continue to keep buyers away. Here's what to know.

The feud reignited on Monday when Musk, who spent hundreds of millions on Trump's re-election, renewed his criticism of Trump's tax-cut and spending bill, which would eliminate subsidies for electric vehicle purchases that have benefited Tesla, the leading U.S. EV maker. That bill passed the Senate by a narrow margin midday Tuesday.
