He has been a terrible candidate though. If the polling is accurate and trump has a slight lead in popular vote, Biden has less than a 5% chance of winning the election (according to Nate Silver’s models). Unfortunately, this is probably optimistic as polling has overestimated the democratic vote in the last 2 presidential elections including the one that included these same two candidates.
Growing up my mom didn’t understand this and always insisted that the sink plungers were the only kind that worked (she also called them toilet plungers) and that toilet plungers (the fancy kind) were some kind of trick. Took until I was in college that I learned you shouldn’t have to break a sweat unclogging your toilet.
