Jon Ossoff, a rising star in the Democratic party who has been cited as a potential presidential contender in 2028, has been re-elected to the Senate in Georgia, defeating Mike Collins, his Republican challenger.

The senator made his re-election campaign a referendum on the Trump administration’s misdeeds, highlighting self-serving stock trades and business deals by the president and others in his orbit, as well as the consequences of the war in Iran and Trump’s trade policies on the finances of Georgia’s voters.

Democrats are on the brink of returning to the majority in the US Senate, after their candidates won historic victories across the United States in a sweeping repudiation of Donald Trump.

Democratic victories in Texas, Ohio, North Carolina and South Carolina, projected by the Associated Press, will give them control of the chamber, assuming they can hold on to all seats they currently hold. It was a stunning turnaround for the party, two years after voters put them into the minority in Congress’s upper chamber as they returned Trump to the White House.

Former US president Barack Obama mocked Donald Trump’s “whole of government” response to his critique of his successor’s gilded White House renovations as he rallied Democrats in the final week of the US midterm election campaign.

“These are not serious people,” Obama said of Trump and the Republican party at a campaign rally in suburban Atlanta on Wednesday evening. “And we’re all paying the price for their lack of seriousness.”
