Vice President Kamala Harris and former President Donald Trump enter the final weekend of the most tense US presidential campaign of modern times with a flurry of swing-state rallies that will test their stamina — and ability to persuade the country’s last undecided voters.

Harris, bidding to become the country’s first woman president, will use rallies in Georgia, North Carolina and Michigan to drive home her message that Trump is a threat to US democracy.

Trump — seeking a sensational return to the White House after losing in 2020 and becoming the first presidential nominee to have been convicted of crimes — promises a radical right-wing makeover of the government and aggressive trade wars to promote his policy of “America first.”

The 78-year-old, who rallied in Milwaukee, Wisconsin late Friday just miles from Harris’s event there, will all but cross paths with her again as Trump makes whistle-stops in North Carolina, Virginia, Pennsylvania and Georgia.

Their frenetic schedule will run right into Monday, culminating with late-night rallies — in Grand Rapids, Michigan, for Trump and Philadelphia, Pennsylvania, for Harris.

Election Day is Tuesday but Americans have been voting early for weeks, with more than 70 million ballots already cast — including a record four million in Georgia, where Democrats seek to pull out all the stops to keep the state in their column.

Opinion polls continue to show a tied race, particularly in the seven battleground states likely to determine the result in the US electoral college system, leaving the Republican businessman and his 60-year-old Democratic rival fighting hard to peel off even slivers of support from one another’s camps.

Harris, currently President Joe Biden’s vice president, is doing that by appealing to centrist voters and propelling her base to the polls with a robust ground game and get-out-the-vote effort.

And by painting Trump as a toxic authoritarian, she is also encouraging voters to “finally turn the page” on the former president.

“He is someone who is increasingly unstable, obsessed with revenge, consumed with grievance — and the man is out for unchecked power,” she told supporters in Little Chute, Wisconsin.

Thrill ride

Trump, meanwhile, has doubled down on his already extreme rhetoric in hopes of firing up his loyal base to turn out in massive numbers.

“Kamala’s closing message to America is that she hates you,” Trump fumed on Friday night in Warren, Michigan, where he trashed the economy under Biden and Harris as a disaster — which economists say it clearly is not — and warned that “a 1929-style economic depression” would ensue if Harris were elected.

Citing her hawkish foreign policy views, Trump conjured up the image of former Republican representative turned Harris supporter Liz Cheney being shot.
