Trump, Biden clinch enough delegates for US presidential nomination

Joe Biden and rival Donald Trump each won enough delegates Tuesday to clinch their party nominations in the 2024 presidential race, networks projected, all but assuring a rematch and setting up one of the longest election campaigns in US history.Biden essentially raised the curtain on his re-election campaign last week during his set-piece State of the Union speech in which he sought to reassure voters about his age and launched a scorching attack on his "dangerous" election rival.
