Who are the people that cast the official votes for electing the vice president or president of US?

Answer 1

Nominations are officially made by the delegates to the nominating conventions held by the respective political parties. Some of the delegates are bound to vote on the first ballot in accordance with previously held state primary election results.

Answer 2

The President and Vice President are elected by the 538 electors appointed by the 50 states plus D.C., but only if one candidate in each race has more than half of the votes (at least 270). The way each state's electors vote is based on the popular vote within their state. They cast their votes on the Monday that falls after December 12 and before December 20.

In the case where no Presidential candidate has more than half of the electoral votes (like in 1824), the House of Representatives elects the President from among the three candidates with the most electoral votes. Each state casts one vote, no matter how many Representatives that state has in the House. Again, someone needs more than half of the votes (26) to win.

In the case where no Vice Presidential candidate has more than half of the electoral votes (like in 1836), the Senate elects a Vice President from between the two candidates with the most electoral votes. (A clear winner needs more than half of the votes.)

Congress repeats their election until a clear winner is determined.
Technically, the Electoral College elects the president. The president is not chosen by the popular vote, but the members of the Electoral College are elected by popular vote. They run as backers of a specific candidate and almost always vote the way the said they would. In same states, they are not legally required to vote any certain way there have been cases when electors betrayed their party affiliation.

The number of electoral votes for each state is dependent on the state's population. Because of this, there have been occasions when one Presidential candidate has won the national popular vote or carried the vote in more states, but lost the election because the other candidate won in enough high-population states to carry the electoral vote. This is why certain states receive more campaign and media attention than others prior to a major election. The related link highlights the swing states for 2012.

Answer 3

Electoral votes in the Electoral College determine the President and Vice President of the United States. Every state and DC are awarded a certain number of electoral votes with which to elect the President. Each state has electoral votes equal to the total of the 2 representative the state has in the U.S. Senate plus the number of representative the state has in the House of Representatives. The states choose as many "electors" as it has electoral votes and these "electors" elect the president and vice president. The "electors" are elected by popular vote in each state and each candidate for "elector" swears in advance whom he will vote for.
