Trump and Biden’s Michigan visits will present competing strategies for winning union voters

When United Auto Workers went on strike against General Motors four years ago, Joe Biden and Donald Trump took very different approaches.

Trump, the incumbent Republican president who’d clashed with unions over his labor policies, told reporters at the time he had a good relationship with autoworkers and he hoped the two sides would reach a deal quickly. Biden was one of several Democratic presidential candidates visiting striking workers, criticizing GM for failing to share rising profits with workers.
