re: Trump and Biden Schedules for the next several days

I was wondering about the money given to the candidates in this election. Biden supposedly has out raised Trump by over a 100 million. I can see Trump spending his money on travel and rallies. But with Biden staying in his basement and not even going a distance to buy milk and bread at the store where is all that money he received going? Soros has given more than 80 million i hear. Correct me if I am wrong.
