Explainer | US presidential election 2020: how the Electoral College picks the winner
- A candidate becomes US president by securing most ‘electoral’ votes rather than winning the popular vote
- Efforts to modify or abolish the Electoral College system, which originated in 1787, have not succeeded

“Beautiful” is how US political outsider Donald Trump described his shock presidential win against rival Hillary Clinton on the night of November 8, 2016. The details were less clean-cut.
Former secretary of State Clinton had received nearly three million more votes than her Republican rival.
But, by narrowly winning key battleground states, Trump surpassed the 270 Electoral College votes necessary to win the White House.
With the 2020 election on November 3 featuring Trump and Democrat Joe Biden, the rules of this enigmatic – some argue outmoded – system are coming back into focus.
Why an Electoral College?
The 538 members of the US Electoral College gather in their state’s respective capitals every four years after the presidential election to designate the winner. The popular vote in each state typically determines which candidate receives a state’s electoral votes.
