Joe Biden has officially clinched the Democratic nomination for the upcoming US presidential election, according to reports from Edison Research. On Tuesday night, Biden surpassed the required threshold of 1,968 delegates needed to secure the nomination. This paves the way for a historic face-to-face battle between the former and current presidents in the country's first such matchup in 70 years.

Reuters reported that Biden's confirmation came after he reached the necessary delegate count, effectively becoming the Democratic Party's candidate for the November election. With no strong challengers in sight, it was widely expected that the current president would secure the nomination. This was solidified following the Georgia primaries, where Biden garnered the required support from delegates in the state. Throughout the primaries and caucuses, Biden consistently emerged victorious, further solidifying his position as the Democratic frontrunner.

Meanwhile, on the Republican side, it is all but certain that Donald Trump will be nominated as the party's candidate. The former US president demonstrated his dominance in the primaries by winning 14 out of 15 states during the recent 'Super Tuesday' polls held last week.

As the stage is set for a showdown between Biden and Trump, the American electorate awaits what promises to be a closely watched and highly contentious presidential election.
