In the last month, there has been little movement in the battleground numbers, even with millions in advertising expenditures from the Trump campaign. The state polling numbers in 2020 are more reliable with multiple polls conducted by national media outlets.
The President improved his position by a point in Arizona and Michigan, two points in Florida, and his biggest gain of four in North Carolina, going to three points for Biden to one for Trump. He lost a point in Pennsylvania and Wisconsin. I’ve added Ohio to the watch list. Trump won it by 8 points in 2016 and is now behind by 2 points.
