Tuesday is election day in the United States. The president is decided by who wins a majority of the electoral college votes. Each state is awarded a certain number of electoral votes (calculated by the number of Senators from the state -2- plus the number of members of the House of Representatives in that state). There are a total of 538 electoral votes and the candidate who gets the most votes in a state wins that state's electoral college votes. A candidate needs to win 270 electoral votes to win the presidency.
Here is a map showing the current polling numbers. If a candidate has a lead of over 5% in a state, the state is shown as "leaning" to him and if his lead is over 10%, it is shown as a "likely" state for him. A lead of over 15% is shown as "solid" for that candidate.
