President Trump campaigned in 2016 on a pledge to restore jobs — manufacturing jobs, specifically — to long-struggling Midwestern communities, and he has made the economy a centerpiece of his re-election campaign.
But job growth has slowed sharply this year in Michigan, Pennsylvania and other states that were critical to Mr. Trump’s victory in 2016, as well as in states like Minnesota that he narrowly lost. Hiring in the region has remained sluggish even as it has picked up this fall in much of the rest of the country. Other economic measures show similar weakness.
