One poll is never very good news.
I don’t usually look at state-level polling because it is less accurate than national polling, but in deference to contrary opinions, I just did an analysis of where the race stands in Michigan and Pennsylvania.
This uses official returns I found at cnn.com, and the fivethirtyeight.com averages of “presidential general election polls, accounting for each poll’s quality, sample size and recency.”
Michigan
Biden won the state of Michigan by just 2.8 percent in the 2020 popular vote, despite being up by 7.9 percent in the final (November 2) pre-election 538 Michigan polling average.
538 had Biden ahead by 6.8 percent, in Michigan, on April 29,2020.
538 has Trump ahead by 2.1 percent, in Michigan, on April 29, 2024.
So Biden is 8.9 percent behind where he was at this point four years ago. And, if skews stay the same, Biden needs to make up 6.1 percent in Michigan to tie.
Pennsylvania
Biden won my commonwealth of Pennsylvania by just 1.2 percent in the 2020 popular vote, despite being up by 4.7 percent in the final (November 2) pre-election 538 Pennsylvania polling average.
538 had Biden ahead by 5.6 percent, in Pennsylvania, on April 29, 2020.
538 has Trump ahead by 1.7 percent, in Pennsylvania, on April 29, 2024.
So Biden is 7.3 percent behind where he was at this point four years ago. And, if skews stay the same, Biden needs to make up 6.1 percent in Pennsylvania to tie.
It’s a coincidence that Biden is, by this method, behind by 6.1 percent in both states. But what isn’t a coincidence is that Biden keeps on running about that much behind four years ago, both nationwide and in these swing states. It bumps a point or two this way or that from time to time, but I still see a static race with Biden behind.
Will campaigning push the race outside this narrow range? Pretty unlikely historically, I think. Debates help Biden, but that is already taken into account in my admittedly imperfect method. Do unpredictable events matter? Yes. Would being convicted of a felony push the race outside of this narrow range? Since it never happened before, no one knows, but, more likely than not, we’ll find out.
