Odaily News Biden's speech at the NATO summit did not completely quell doubts about his health, and now there is new pressure, and his betting odds have also dropped. The betting website PredictIt shows that his chances of winning the Democratic Party's presidential nomination are less than 50%. The main catalyst for the decline in his nomination odds seems to come from two figures. One is that former House Speaker Pelosi did not explicitly express her support for Biden. As an "old player", Pelosi may know which way the wind is blowing. Second, Hollywood actor George Clooney, a long-term Democratic donor, published an opinion article in the New York Times, saying, "The Joe Biden who was with me at the fundraiser three weeks ago is no longer the great Joe Biden of 2010. He is not even the Joe Biden of 2020. He is the guy we saw in the debate. With this president, we will not win in November."
