Arch rivals Donald Trump and Kamala Harris are embarking on a final campaign blitz with both hitting must-win Pennsylvania on the last day of the most volatile US presidential election in memory.
On the election day, polls suggest deadlock in surveys nationally and in the seven swing states where the result is expected to be decided.
Kamala Harris will spend the whole day campaigning in Pennsylvania, culminating in a massive rally in its biggest city Philadelphia featuring singer Lady Gaga. Donald Trump will travel to North Carolina, Pennsylvania and then Michigan.
In a sign of how crucial Pennsylvania is to their chances of occupying the Oval Office, Trump and Harris will even hold duelling rallies in the industrial city of Pittsburgh. Pennsylvania is the single biggest swing state prize under the US Electoral College system, which awards influence in line with population.
