³Trump is so far projected to win 23 states, including Texas, Ohio and must-win Florida, having outperformed pollsters’ predictions

⁶His campaign calls President’s Trump statement “outrageous”, adding: “The counting will not stop”
⁷The US is on course for its highest turnout in more than a century, and we might not have a result for days
US Election: Previous presidents who won through Electoral College votes
In the US, a presidential candidate can lose the popular vote but still win the election as it is the Electoral College that determines the winner • Under the system, “electoral votes” are allotted to 50 states in the country and the District of Columbia based on its population • Some of the presidents who won through the process were George Bush, Benjamin Harrison and the current Head of State Donald Trump.
