On June 30th, Jinshi Data reported that according to BBC, US President Biden promised to Democratic donors that he can still defeat Trump and win the presidential election. His poor performance in the debate raised concerns about his qualifications as a candidate. The 81-year-old Biden participated in a series of fundraising events in New York and New Jersey on Saturday and defended his performance in the CNN presidential debate. At one of the events, Biden said, 'I don't have a great dream, but neither does Trump. I assure you that we will win this election.' He said he understood people's concerns about his performance in Thursday's debate, but he promised to fight harder.
