Donald Trump has been elected to return to the White House as the 47th United States president.

The vote was called for the Republican candidate by The Associated Press news agency early on Wednesday. His victory has been met by international congratulations but is likely to add further uncertainty to a turbulent geopolitical situation.

Results showed Trump beating Vice President Kamala Harris in a race far less tight than expected as he triumphed in key battleground states.

Victory in Wisconsin after earlier triumphs in Georgia, North Carolina and Pennsylvania saw the former president clear the threshold of the 270 Electoral College votes required to clinch the White House in Tuesday’s election.

Trump’s victory in those swing states currently sees him with 277 electoral votes against 224 for Harris. Polls had predicted a much tighter race, but it appears that anger fuelled the Republican’s remarkable comeback from defeat in 2020 and widespread condemnation of his refusal to accept the result.

That refusal sparked a violent insurrection at the US Capitol, and Trump was also convicted of felony charges and survived two assassination attempts.

However, his campaign, which has seen him demonise his political opponents, immigrants and many minorities, tapped into the frustrations of many voters in a bitterly polarised nation.

Speaking to his supporters as he declared victory, Trump claimed he had won “an unprecedented and powerful mandate”.

Anger and resentment

Scott Lucas, a professor of international politics at the University of Dublin, told Al Jazeera that Trump’s victory stemmed from frustrations that have been bubbling within the American public for years.

“There is anger and resentment in the US, which has been there for quite some time. It’s been a trauma since 9/11. It’s been there with the financial crash in 2008-2009. It was there in 2016 when Trump exploited it, and he exploited it again,” Lucas said, adding that Trump was able to do that because the “political system is damaged”.

Concern over the economy, and inflation in particular, under President Joe Biden was a major focus of Trump’s campaign.

That also encouraged opposition to the support Washington is giving to Ukraine in its war against Russia. Meanwhile, the failure to rein in Israel’s wars on Gaza and Lebanon has angered Muslim and liberal voters.

Those complex geopolitical issues will test Trump, who is known for his simplistic claims of being capable of quickly solving such issues.

He has promised to end the war in Ukraine in a day, an idea that has Kyiv wary that it could face pressure to strike a deal to hand over territory to Russia. NATO allies, meanwhile, fear Trump will weaken the alliance’s mutual defence guarantees.

Trump is also a strong supporter of Israeli Prime Minister Benjamin Netanyahu and has boasted he will end the war with Hamas in Gaza in hours.
