The 77-year-old was given 251 electoral college votes, with Trump unable to overturn Biden’s 2020 lead in Arizona, Pennsylvania and Wisconsin.

However, Trump was less than half-a-point behind his Oval Office successor across the three swing states.

Victory for the 45th President in Pennsylvania would prove enough for him to become just the second Commander-in-Chief to serve non-consecutive terms in the White House.

Stack Data Strategy poll, which was seen by The Daily Mail, suggested election day is now on a “knife edge”.

Joe Bedell, head of Stack Data Strategy, said: “The 2024 election cycle is truly on a knife edge.

LATEST DEVELOPMENTS:

“According to our in-depth research, President Biden is currently on course to cling on in the White House.

“But this is only by the narrowest of margins: only a percentage point in some states.

“The Midwest states that took Donald Trump to victory in 2016 are sticking with Biden for now, but it is effectively a toss-up in many of these key battlegrounds – there is everything to play for and every vote will count.

“The race for Congress is just as tight with the Republicans currently set to regain the Senate and retain control of the House. This is going to be a truly nail-biting contest.”

Biden appears to have turned around his fortunes since Stack Data Strategy’s November survey found he was leading in the popular vote and trailing in the electoral college.

Trump won the 2016 election even though he was languishing behind Hillary Clinton in the popular vote.

George W Bush was the only Republican nominee to obtain more votes than their Democratic rival in any election held since 1992.

Biden’s position is being bolstered by the 46th President making gains with older, white, rural, suburban and lower-educated groups.

However, the 81-year-old continues to struggle with 18 to 24-year-olds.

Stack Data Strategy interviewed 7,793 US registered voters online between March 27 and April 10.
