[Biden was exposed to "cut off source of campaign funds" and fell into a "catastrophic" dilemma] On July 12, according to a report by Reference News citing the website of the National Broadcasting Corporation of the United States, sources said that US President Biden's campaign has faced the problem of reduced donations and the situation is extremely dangerous. The report said that one of the sources said: "The situation is catastrophic." Another source said: "The source of funds has been cut off." Two other sources said that this month, Biden's campaign fundraising from big donors may be reduced by half or even more. A source said: "Donors are very negative. They talked to the president. The call seemed unnatural to people, and I don't think they believe him." According to reports, the US media unanimously agreed that Biden performed poorly in the first debate with Republican Trump in Atlanta on the evening of June 28. Now, politicians and reporters are saying that the Democrats may refuse to nominate Biden and replace him with other candidates. In theory, the party will have such an opportunity at the August convention, but in reality, it is difficult for Biden, who won the primary election, to withdraw from the campaign unless Biden gives up himself. At the same time, the current president's campaign team said that Biden will not give up and withdraw from the campaign. There are reports that he could be nominated as early as July 21, rather than waiting until the Democratic convention in August, ending the debate over whether he should run. The second debate between Biden and Trump is scheduled for September 10. The US presidential election will be held on November 5.
