Is the Democratic candidate underperforming in swing states relative to national polling?
Core argument: Polls show Kamala Harris underperforming in swing states relative to her national numbers, a recurring pattern in the Silver Bulletin forecast, especially in Pennsylvania.
Another day, another set of polls showing Kamala Harris underperforming in swing states relative to her national numbers. No, it’s not from the world’s best pollster, but this has been a theme lately, especially in Pennsylvania. Yes, Harris’s forecast — remains subject to a convention bounce adjustment, although the impact is decreasing a bit. But Trump has been gaining ground on her in most of our state polling averages, too — and they aren’t impacted by the convention bounce adjustment at all.
