Donald Trump and Joe Biden swept up more delegates in Tuesday’s primary elections as they set their sights on a rematch in November.

Trump and Biden’s first victories came in Ohio, where there is also a heated Senate race brewing, and in Illinois. Trump also won the Republican primary in Florida, where the Democrats are not holding a primary.

In Ohio, Illinois and Florida, the former South Carolina governor and presidential candidate Nikki Haley still captured a sizable fraction of the Republican vote, despite no longer being in the race.

The president and former president had already won enough delegates to capture their parties’ presidential nominations, and most of their challengers have dropped out. Trump’s last Republican challenger, his former UN ambassador Nikki Haley, ended her presidential campaign after Super Tuesday. Biden’s long-shot challenger, the Democratic congressman Dean Phillips, dropped out as well.

With the presidential nominating contests clinched, the candidates were focusing on campaigning in swing states they will need to win the general election in November.

In recent days, Biden visited Arizona and Nevada, where he is looking to shore up the support of young and Latino voters who could be key to his re-election. Biden is touting economic policies and attacking Trump on immigration and abortion as he seeks to win over wavering voters and waning enthusiasm among groups that backed him in 2020.

Democrats seeking to register frustration with Biden over his handling of the war in Gaza are urging supporters to vote for the self-help guru Marianne Williamson in Arizona – as she, unlike Biden, has called for a permanent ceasefire. Pro-Palestinian protesters in Ohio, meanwhile, are urging supporters to “Leave It Blank”.

Trump, meanwhile, has continued to court controversy on the campaign trail amid ongoing legal troubles. He claimed that Jewish people voting for Democrats “hate their religion” and Israel, in an interview on Monday – drawing outrage. As he criss-crosses the country to rally supports and raise funds, he has also increasingly made the January 6 attack on the Capitol a cornerstone of his campaign, saluting rioters as heroes.
