Former US President and 2024 presidential hopeful Donald Trump speaks at Drake Enterprises, an automotive parts manufacturer and supplier, in Clinton, Michigan, on September 27, 2023. Both Trump and Biden are visiting Michigan this week, in what is their first major skirmish of a long fight for voters in working-class swing states ahead of the November 2024 election. Biden on September 26, 2023, became the first sitting president to stand on a picket line, supporting calls by the United Auto Workers (UAW) union for the Big Three Detroit carmakers to raise wages. And Trump is skipping a debate in California with his trailing Republican rivals on September 27 to head instead for a small, non-union car parts factory on the other side of Detroit.
