Republicans projected to retake control of US Senate

Republicans are projected to have retaken control of the US Senate, after flipping Senate seats in West Virginia and Ohio.

The projected results move the Senate to a 51-49 split in favour of the Republicans.

Jim Justice, West Virginia's current governor, is projected to win the seat vacated by the former Democrat Joe Manchin, while Bernie Moreno in Ohio unseated Democratic incumbent Sherrod Brown.

In the House of Representatives, Republicans so far are leading - though several races are still undecided.

If the Republican Party controls the House, Senate and the White House, it would have broad power to pass laws and enact the president's partisan agenda.

Republicans last won a majority in the Senate in 2018.

In Ohio, Brown was projected to lose to Moreno, a Colombian immigrant and former car sales magnate who portrayed the veteran politician as "too liberal for Ohio".

The contest was called the most expensive Senate race in US history.

Brown told supporters that the result was a "disappointment but not a failure", adding: "I'm not giving up on our fight for workers and I know you won't either".

The seat in West Virginia is projected to flip Republican. It was contested after the retirement of Manchin, who frequently clashed with members of his own party before turning independent.

Justice had himself been a Democrat before switching parties to Republican at a Trump rally in 2017.

A total of 34 Senate seats were being contested on Tuesday.

In Texas, Trump ally Ted Cruz fended off a robust challenge from former NFL player Colin Allred to win a third term.

Democrats launched a concerted effort to beat Cruz, but the party has not won a state-wide election in Texas for more than 30 years.

Republicans also retained Nebraska's seat for incumbent Deb Fischer, after a surprisingly fierce challenge from auto mechanic Dan Osborn, a registered independent.

The Senate result immediately kicked off discussions about who would replace Kentucky Senator Mitch McConnell to become the Senate Majority Leader in the next legislative session.

McConnell, 82, announced earlier this year that he was stepping down from the powerful role.

Rick Scott, a Republican incumbent in Florida, who retained his seat despite a challenge by former Miami-area Rep Debbie Mucarsel-Powell, a Democrat who migrated from Ecuador as a child.

Speaking at a victory rally early Tuesday evening, Scott correctly predicted that Republicans would seize the majority in the Senate, adding that he would be selected as Senate Majority Leader.

"Florida is the centre of the Republican Party of this country," he told the crowd. "Washington can learn a hell of a lot from what we've done right here in this great state."

Democrats held a seat in Delaware, a state that President Joe Biden represented as a senator for 36 years, with a victory for fourth-term Congresswoman Lisa Blunt Rochester.

In Maryland, the Democrats retained a seat vacated by Ben Cardin, with Angela Alsobrooks beating the popular Republican Governor Larry Hogan.

They will become the first black female senators to represent their respective states.

In New Jersey, Democrats retained a seat that was vacated by Bob Menendez, who resigned after he was found guilty of accepting bribes for political favours. Andy Kim, 42, will become the first ever Korean-American senator.

In California, Rep Adam Schiff, who led the first of two impeachment investigations against Trump, retained a seat held by late Democratic Senator Dianne Feinstein.

Other contests that could have swung control of the upper chamber were taking place in Arizona, Pennsylvania, Montana, Michigan, Nevada, Nebraska and Wisconsin.

Both parties are also vying for control of the House, although the balance of power there will not be known for several days.

The vast majority of House elections are happening in "safe districts" - regions where one party is nearly certain to win. But a handful of other races in swing districts could determine who controls Washington DC.

House races that could swing the balance are taking place a wide variety of states, with closely watched elections happening in California, New York, Washington, Maine and Alaska.
