Hillary won the popular by 2% in 2016
Biden by over 4% on 2020
If polls are tied or Trump in the lead Biden is toast
Biden can only go down further as the illegals commit more crimes and are spread to every town pissing off people who pay school taxes for illegals, then as inflation grows ad food is too expensive, market drops when recession takes hold, Biden cannot win. The Dems know this. His dementia is not getting better. Look for a late game substitution. Possibly even at the convention, they have superdelegates who can basically pick their nominee.
