The US presidential election on Tuesday could hinge on approximately a dozen swing states where the contest between Republican Donald Trump and Democrat Hillary Clinton is particularly tight.
The victor should get into the magic number of 270 electoral college votes — but hoping to anticipate the outcome is a complicated exercise in subtracting, adding and blending.
A total of 538 electoral votes are in play, corresponding to the whole number of elected representatives in Congress (435 members of the home and 100 senators) and three to the US capital Washington, DC.
Those who win a state’s popular vote are apportioned the state’s electors, the number of which is approximately based on its population’s size.
Florida is the mother of all swing states, together with 29 votes. It may make or break a candidate, like in 2000, if a few hundred votes separated Democratic rival Al Gore and president George W Bush.
Pennsylvania, with 20 electoral votes, and Ohio, with 18, are key, along with Colorado, North Carolina and Arizona.
Potentially, candidates could forge a path by winning states such as Nevada, Iowa and New Hampshire — or simply by winning a country that voted for the opposing camp.
Here’s a list of the major swing states, the number of electoral votes as well as the averages of recent polls through November 4 at a four-way race — such as the outsiders, Libertarian Gary Johnson and Green candidate Jill Stein, and that won the nation in the last two elections:
