President Joe Biden and former President Donald Trump are on the brink of securing their party nominations as they gear up for a historic presidential rematch, marking the first such event in nearly seven decades.

In four states, including Georgia, the battleground state where Trump faces criminal charges over the 2020 election, primaries are being held. Trump’s dominance in Super Tuesday‘s contests led to the withdrawal of his last rival, former U.N. Ambassador Nikki Haley, further solidifying his position as the presumptive Republican nominee.

Meanwhile, Biden faces token opposition in the Democratic primary, with some Democrats expressing discontent over his stance on Israel’s Gaza conflict. Both candidates have shifted focus to the general election, holding rival rallies in Georgia.

Trump continues to propagate claims of electoral fraud, while Biden emphasizes themes from his recent State of the Union address, criticizing Trump’s rhetoric on migrants. The Biden campaign has launched an aggressive phase, with a significant ad buy and a fundraising boost following his speech.

As of Monday, Trump needs 139 additional delegates to secure the Republican nomination, while Biden lacks 113 delegates for the Democratic nomination. Tuesday’s primaries will allocate a significant number of delegates, setting the stage for the final nomination push.
