Here is my take: I don’t think Joe Biden will withdraw. His backers will hope that most of the country won’t ever see the news on the Hunter Biden laptop scandal. Fox and OANN will cover the story, but CNN, NBC, ABC and almost all others will say little if anything about it. Still, they are worried about the damage this story is causing to Biden, because they know that some undecided voters do tune into Fox sometimes. But they are calculating that the damage won’t be enough to cost Biden the election, and they probably have their own surprises against Trump in the next two weeks.
At this point, you'd have to be drooling in a cup not to be aware of all this.
