My guess on the GOP side is Trump will easily be nominated if he wants the job. However, on the Dem side, not really sure. Biden is clearly suffering severe dementia. He often looks lost or unfocused, which is exactly how people with dementia behave. Spent the last 10 years with a mother that had dementia, so I have seen it first hand, and Joe Biden is clearly suffering dementia. I would expect that Dems will use the 23rd amendment to get rid of him, if he does not "die" first. My guess is that he will die from "natural" causes long before campaigning ramps up.
