One last push from Kamala, Trump before presidential election today

Both are campaigning in Pennsylvania, signifying its importance to enter the White House

- 

BITTER rivals Kamala Harris and Donald Trump embark on a final frenzied campaign blitz on Monday with both hitting must-win Pennsylvania on the last day of the tightest and most volatile US presidential election in memory.

Republican Trump has promised a "landslide" as he seeks a sensational return to the White House, while Democrat Harris said the "momentum" was on the side of her bid to be America's first woman president.

But the polls suggest a different story on the eve of Election Day - total deadlock in surveys nationally and in the seven swing states where the result is expected to be decided.

Now a race of dramatic twists, including two bids to kill Trump and Harris's shock late entrance, is coming down to the most viciously fought-over battleground.
