 More than half of Americans in a new poll say President Biden is not fit to serve another term in the Oval Office. Lisa Taylor has more. The Yahoo News YouGov survey found 60 percent of respondents said Biden is unfit for another term, while just 24 percent said he is fit and 16 percent said they're unsure. Meanwhile, 46 percent said Donald Trump isn't fit for a second term. The results come nearly a week after Biden's poor debate performance in which he stumbled over his words and appeared to lose his train of thought at times.
