Both states played crucial roles in Trump’s victory in 2016. He won Pennsylvania with 48.8 percent of the vote, compared with Hillary Clinton’s 47.6 percent. In Michigan, Trump won with an even narrower lead, getting 47.6 percent of the vote, compared with Clinton’s 47.3 percent.
The Fox News polls were conducted from Saturday to Monday via landlines and cellphones. Poll organizers used a sample of 756 Michigan voters and 793 Pennsylvania voters, and the results had a sampling error of plus or minus 3.5 percentage points.
