Not sure this makes sense. I think the window shifts right as people continue to vote right.

From the Wikipedia article about the Overton window:

The most common misconception is that lawmakers themselves are in the business of shifting the Overton window. That is absolutely false. Lawmakers are actually in the business of detecting where the window is, and then moving to be in accordance with it.

I read over Biden’s statement, and it makes sense to me. Hunter was singled out for political purposes. It would seem weird if Biden didn’t issue the pardon.
