The Pennsylvania poll shows that Harris has a narrow lead with 49 percent of support compared to former President Trump’s 46 percent of support. Another 2 percent of respondents chose another candidate, according to the poll.

Which means the new poll number seems a little funky. Yes, Trump is controversial, and yes, those few high-profile Republicans have endorsed Harris. But in other polls, Trump has GOP support well over 90%.

The battle for union workers is particularly pronounced in Michigan, the hub of American car production, where Harris barely leads Trump. JD Vance stopped in Detroit on Tuesday, promising to invest in auto workers. Last week, Harris ripped Trump for the closure of a Michigan auto plant when he was in office.
