Joe Biden had $9 million in his campaign bank account at the end of September, reports Reuters.

That is significantly less than his top rivals for the 2020 Democratic presidential nomination.

While Biden leads most national public opinion polls, he has struggled to raise money.

Biden is relying heavily on wealthy donors who can write five-figure checks, not smaller individual donations.

Biden has dismissed that his low cash balance is going to be a problem going forward.

He says that his campaign launched after several others, forcing him to catch up to his rivals.
