THE Democrats have swept to an emphatic win in both the US Senate and House of Representatives overnight, in a massive rebuke for President Trump’s policies and ‘Trumpism’ in general.

As of 3.45pm Australian time, the Democrats held 53 Senate Seats and 217 seats in the House of Representatives – 218 are needed for control – with eight Senate seats and more than a dozen Lower House seats yet to be decided.

The result shatters Trump’s mandate and turns intense scrutiny on his final two years in power before retirement.

Earlier, there was a strong view that Democrats would secure the House of Representatives majority, but many analysts were less confident about results in the Senate.

It’s only the third time in US political history that a sitting US president has lost control of both the Senate and House of Reps in mid-terms.

In a monumental rebuff for Trump’s policies and general demeanor, Democrat candidates swept to dozens of Senate victories, including unlikely states like Kansas, held by the Grand Old Party since 1932, and Texas, held since the 1980s.

Voters also delivered dozens of House of Representatives seats to Democrats for a healthy majority there, defying the huge financial advantage that donors including Elon Musk and venture capitalists Marc Andressen and Ben Horowitz directed towards Republican candidates in the most expensive US election on record.

Words like ‘wipeout’, ‘stunning’ and ‘astonishing’ were being used to describe the result by political analysts this afternoon.

Trump retains control until the new Congress year starts in January, however his presidential powers of veto could still create legislative gridlock for the next two years.

Trump’s tariff policies were frequently mentioned by political analysts on US television coverage aired in Australia this afternoon, along with fuel and cost of living challenges, his handling of the economy, policies in the Middle East and the Iraq War, health, immigration and a raft of other social issues.

Earlier this afternoon Trump indicated that he was ‘willing to accept’ the results.

“We’ll work with the Democrats, and we’ll, you know, look forward to working with them. We’ll probably work something out,” he told the New York Times.

“The American people have rebuked the depravity, corruption and incompetence of the failed lame-duck president Donald J. Trump,” successful Democrat candidate Jon Ossoff from Georgia, told his supporters.

Sen elect Ossoff, whose mother is Australian, is being talked about as a potential Democrat candidate for the 2028 Presidential election.

“If, at times, these last two years, amidst the ceaseless onslaught of brutality and indecency, you doubted whether our republic would survive, let tonight’s results give you courage that the first light of dawn is on the horizon.”

Americans turned out in high numbers for Tuesday’s mid-term vote (US time), using the ballot box to embrace a new generation of centre-left leaders while also punishing Trump over his presidency.
