You can keep saying this - that Biden "molests children" - and there is not a shred of evidence it's true. I've even watched the (creatively edited) videos you are referring to, because some of my Trump-supporting family got into it with me. One can say, at very worst, that he was too eager to put arms around them or speak close to their ears, for someone they didn't know. There is just nothing there.
The only people outraged now, or who will be outraged later, by those videos, are people already bound and determined to support Trump. Which make is a non-issue for the election.
Have you see the comparison of per capita curves for Iowa and Minnesota? They were identical up until the day that MN (and other states) put in place more stringent controls. They are neighbor states with similar cross-sections, especially if you take Minneapolis out of the equation. And starting within a few days of MN's order and Iowa's decision not to lock down, Iowa's curve skyrocketed in comparison in MN. And MN is slightly denser in population so all else equal they SHOULD have been hit harder. It's one of the best, clearest examples of how the shelter in place orders work.
