How are Texas electoral college voters selected?

In short: US Presidents are not directly elected by the individual voters but by the Electoral College, whose members pledge their votes to the candidate who won the popular vote in their State. In most States, the candidate with the majority of votes statewide receives all of that State's electoral votes; however, some States allow electoral votes to be divided between candidates.

The number of electors is based on the state's population. The states with the greatest population have the most electoral votes. When the voter casts a vote for president, in reality the vote goes to one of the presidential electors designated by the candidate in that state. The number of electors for each state equals the number of senators and representatives that state has in Congress. Although the number can change based on the census. The candidate who receives the most votes receives all the electoral votes in that state. The candidate with a majority of the electoral votes is elected to office. The electors gather in Washington, DC, in December and cast their ballots based on the results of the November election. If no candidate receives a majority of the electoral votes, the election of president is determined by the House of Representatives.

Presidential elections are held on the Tuesday after the first Monday in November every four years. After the results have been tallied, the Electoral College meets on the Monday after the second Wednesday in December to cast their votes. In most elections, the electors will vote for the candidates that the people chose through the popular vote. However, this is not required by law. The Founding Fathers felt that there would potentially be times when the people would not know which candidate would be the best president, and as a result the electors can choose to vote against the popular vote. Today this is rare, but it is possible.

Some states have made laws that require the electors to vote according to the will of the people. Other states have separate groups of electors for each party, and these electors are bound to vote for the their party's candidate. When the votes are tallied, these states send the appropriate electors to the December vote, thus ensuring that the choice the people made is followed. However, not all states have these provisions, so it is entirely possible for an elector to vote for a candidate that did not win the popular vote in her state.The Electoral College is composed of 538 electors who are tasked with the responsibility of deciding the President and Vice-President of the US.
