The window for a final presidential debate between former President Donald Trump and Vice President Kamala Harris is closing.

The presidential race has tightened in the wake of the debate performance by Ohio Sen. JD Vance, a new national poll shows.

Harris led by 2 points in Michigan (48 percent to 46), and a point in Nevada (48 percent to 47), Pennsylvania (48 percent to 47), and Wisconsin (47 percent to 46). In Georgia the candidates are tied at 47 percent. Trump leads by one point in Arizona (48 percent to 47 percent) and 2 points in North Carolina (47 percent to 45 percent).
