Donald Trump has won in Michigan, completing his rout of the “blue wall” in a landslide election victory that lays the ground for a radical second term in office.

The president-elect won an estimated 49.7 per cent of the vote in Michigan, outstripping Kamala Harris at 48.3 per cent.

Victory in the state confirmed Trump’s clean sweep of the three blue wall states, which also included Pennsylvania and Wisconsin, that Democrats had believed mapped out their clearest path to winning the White House.

The Republicans have won 292 electoral college votes so far, well clear of the 270-vote threshold needed to win the presidential race, and have also reclaimed the Senate. The House has still not been called.

Addressing supporters during his victory speech in Palm Beach, Florida, Trump said the resounding victory had given him an “unprecedented and powerful mandate” to rule.

Trump’s win leaves the Democrats in tatters and his opponent Kamala Harris humiliated after one of the shortest presidential campaigns in history ended in a heavy defeat fuelled by a swathe of unlikely voters.

She conceded the election in a private call to Trump on Wednesday afternoon.
