Four years ago Donald Trump claimed a surprise victory over Hillary Clinton at the 2016 US Election.

Despite polls favouring the Democrat candidate, Trump emerged as the winner on Election night, claiming unlikely victories in Michigan, Pennsylvania and Wisconsin.

The incumbent President will likely need to claim victories in the same battleground states if he is to beat 2020 rival Joe Biden.

Voter turnout

At the 2016 election 138,847,000 votes were cast

That’s 55.5% of the voting age population (VAP) with 250,056,000 eligible to vote at the last election.

This was a 0.6% increase on the 2012 election, but a 1.6% drop on the 2008 election.

Forecasts for the 2020 election suggests that 150m Americans could vote, which would represent the highest voter turnout percentage in over a century.

So why the high turnout?

More than ever the electorate feel like the result of the election matters – a poll by Pew Research Center found that 83% of respondents believed that it “really matters who wins” the election, compared to 74% in 2016 and 63% in 2012. This is at least partly to do with Mr Trump’s divisive nature with his loyal base and his bitter rivals determined to emerge victorious this election day following a year dominated by the coronavirus pandemic and Black Lives Matter demonstrations.
