As the race for the White House enters its final day, both sides remain on tenterhooks.Most polls have Hillary Clinton in front, but they still remain perilously close.

The latest polls indicate that Ms Clinton's is between four and five per cent ahead, with a small lead in the key state of Florida.

But another poll of polls has put Ms Clinton on roughly 46 per cent of the vote compared to Mr Trump’s 44 per cent while the ABC News/Washington Post tracking poll has her only one point ahead.

Tellingly, enthusiasm for Ms Clinton’s candidacy is down from 51 per cent to 47 per cent – prompting fears it could depress turnout on 8 November.

The Clinton campaign is reportedly fearful after early voting in several battleground states indicates the African American vote is down on what it was four years ago.

The US election is decided by the Electoral College system which has a total of 538 voters divided up between the 50 states according to population size.

This means the election is ultimately decided by a handful of key “battleground” states across the country even though they do not have the largest number of electoral college voters.

Based on the current distribution of votes in each of these states Ms Clinton looks most likely to win in the Electoral College with polling currently projecting she will win 347 seats to Mr Trump’s 191.
