Congress sets January 7, 1789 as the date by which states are required to choose electors for the country's first-ever presidential election. A month later, on February 4, George Washington was elected president by state electors and sworn into office on April 30, 1789.
As it did in 1789, the United States still uses the Electoral College system, established by the U.S. Constitution, which today gives all American citizens over the age of 18 the right to vote for electors, who in turn vote for the president. The president and vice president are the only elected federal officials chosen by the Electoral College instead of by direct popular vote.
