Detroit: Kamala Harris and Donald Trump began a frantic last push across US swing states Sunday, with less than 48 hours of campaigning left to secure a decisive edge in a bitterly fought and historically close presidential election.

Over 75 million people have cast early ballots ahead of Tuesday's climax and the race is down to the wire -- with more states functionally tied in polls at this point than in any comparable election.

The closeness of the race is all the more remarkable given its dramatic twists -- including an assassination bid and Harris's stunning late entrance -- and the fact that the candidates could hardly be further apart in their campaign styles and visions for the future.

A final New York Times/Siena poll on Sunday flagged some incremental changes in the key battleground states, but the results from all seven remained firmly within the margin of error.

Harris -- desperate to shore up the Great Lakes states seen as essential to any Democratic ticket -- was to spend the day in Michigan, beginning in Detroit before a stop in Pontiac and an evening rally at Michigan State University.
