Demographic changes in the United States have been a compelling factor behind Democratic Party candidate Joe Biden becoming the 46th President of his country. These changes enabled Biden to neutralise to a great degree Republican Donald Trump's campaign largely built around White nationalism or racism, which fetched Trump nearly eight million votes more than he polled in 2016. Trump took one State after another until he was thwarted in the battleground or swing States.

All battleground States have seen a significant dip in their share of non-Hispanic White eligible voters since 2000, according to Pew Research Centre data published in September. For instance, Whites comprised 58 per cent of Nevada's electorate in 2018, down from 76 per cent in 2000 – a fall of 18 percentage points. During the same period, the share of White eligible voters in Arizona dipped by 12 percentage points, and by 10 in Georgia and seven in Pennsylvania. These were precisely the four States where Trump floundered.
