Vice President Kamala Harris has gained significant momentum in the 2024 presidential race, holding a five-point lead over former President Donald Trump, according to a new NBC News poll. Harris' popularity has surged by sixteen points since July, marking the largest increase for any politician in NBC's polling since George W. Bush after 9/11. She now leads Trump on issues of competence and mental and physical health and represents a vision of change favored by voters. However, Trump maintains an edge on the economy and inflation, with 66% of voters citing the cost of living as a top concern.
