Are the two leading candidates splitting key battleground states?
Core argument: Kamala Harris leads Donald Trump 50% to 47% in Pennsylvania in the Times/Siena poll, a margin inside the margin of error and equal to four percentage points using unrounded figures.
In Pennsylvania, Ms. Harris’s polling lead has been steady, though the state remains tight. Her advantage, 50% to 47%, falls inside the margin of error. But this was the third Times/Siena survey in two months showing support for Ms. Harris from at least half of the state. (Her lead in the poll was four percentage points when calculated using unrounded figures.) Fueling Ms. Harris in the state is her commanding lead of nearly 20 percentage points when it comes to handling abortion, her single best issue across battleground states and the second most important concern for Pennsylvania voters. In Arizona, Mr. Trump was ahead, 51% to 46%, or six percentage points when calculated using unrounded figures, nearly unchanged from September, when the poll showed the former president leading, 50% to 45%.
