with just a month remaining until the election, polls in all seven battleground states show the race within the margin of error, leaving the door open for either candidate to potentially sweep all key swing states.

While Harris maintains a slim national lead of 2 to 3 points and holds an edge in four swing states, recent polling has shifted more favorably for Trump.

An ActiVote poll now puts Trump 1 point ahead nationally, and a Fabrizio/McLaughlin poll shows him leading in every swing state. Pollster Nate Silver's tracker shows that Trump has made gains in every swing state other than Georgia in the past week. This momentum raises the possibility of a landslide victory for Trump.

But what constitutes a landslide? There is no precise definition, but political scientist Gerald Hill told the Associated Press that "it usually means exceeding expectations and being somewhat overwhelming."
