DONALD Trump has declared victory in the US presidential race at a campaign event in Florida. 

"This is a magnificent victory for the American people, that will allow us to make America great again," he said in a speech to cheering supporters at a campaign event in Florida. 

It comes after the former president was projected to win the battleground state of Pennsylvania, adding to other key wins in Georgia and North Carolina.

Trump is currently projected to win 266 electoral college votes, just short of the 270 required to officially win the presidency as Harris's route to the White House looks more and more improbable.

The Republican candidate said there was “no other path to victory” for Harris after he won the US swing state of Pennsylvania.

He told his supporters that “America has given us an unprecedented and powerful mandate” and pledged to “fight” for “every citizen” and promised the “golden age of America”.

Trump added: “Every single day I will be fighting for you with every breath in my body.

“I will not rest until we have delivered the strong, safe and prosperous America that our children deserve, and that you deserve.”

Harris’s hopes for the presidency have now all but disappeared, as even with votes from the remaining battleground states – Nevada, Arizona, Michigan and Wisconsin – the odds appear stacked against her.

In central London, Democrat supporters went virtually silent as a television network showed Trump ahead in swing states.

Some held their head in their hands as concern spread about Harris’s prospects, and there were shouts of “No, that can’t be right” as projections on CNN showed Trump strongly ahead among Latino voters in Michigan.

A spokesperson for Republicans Abroad has meanwhile claimed Democrats are on course for a “shellacking” and their path to victory is “getting narrower and narrower”.

Sara Elliot also told Times Radio: “It is definitely not what we expected in some ways, being that the polls were as close as they are.”
