An openly corrupt retard who never in his life polled above 1% got more votes than any candidate in the history of Western Civilization without leaving his house?
I have absolute no idea what you mean with the bolded language. Biden won a buttload of Senate elections over the year in which he clearly had more than 1% support, and the only way he became the Dem nominee is because of support in obvious excess of 1%.
But that's all tangential to the real point. Biden did not have to come out of his basement to campaign because nobody voted for Joe Biden thinking he'd be a great president. The votes he got were from people who hated Trump, and weren't offended by Biden.
He won not because he was fantastic, but precisely because he was mediocre, and therefore an acceptable, boring alternative to Trump.
