Joe Biden may come to regret his claim to be pro-union

Both the Democratic and Republican parties are already fairly sure who their nominees will be in 2024, so the general election campaign will begin unusually early. Perhaps it started this week: President Joe Biden joined a picket line in Michigan, becoming the first sitting president to do so; the next day Donald Trump was in the same state, also courting car workers. As befits a campaign in which the two candidates have a combined age of 157, it has a retro feel. High inflation and striking union workers in Detroit recall races from the 1970s.
