United States Vice President Kamala Harris and former president Donald Trump duelled across the swing states on Saturday marking the final weekend of one of the tensest US elections of modern times.

The Democratic presidential candidate urged voters to “turn the page” on the Republican’s scorched-earth brand of politics.

According to AFP, 75 million people have already cast early ballots as the hours tick down to the Election Day climax Tuesday.

The country — and the world — could then face a nail-biting wait to know whether Harris becomes the first US woman president or Trump secures a spectacular return to power after his unprecedented and at times violent campaign to overturn his 2020 re-election loss to Joe Biden.

The rivals literally crossed paths Saturday, with Harris’s official vice presidential Air Force Two and Trump’s personal jet sharing the airport tarmac in Charlotte, North Carolina.

Both held rallies in North Carolina, while Harris also spoke to supporters in Georgia, another of the seven swing states seen as the keys to victory in an otherwise dead-even nationwide contest. Trump added in a stop in Virginia.

The rounds of high-stakes speeches before thousands of people at each stop continue Sunday when Harris holds multiple events in the swing state of Michigan and Trump rallies with supporters in Georgia, North Carolina and Pennsylvania.

Most polls show Trump, 78, and Harris, 60, within the margin of error from each other across the swing states.
