Why doest the presidential election take place in November?
By federal law since 1792, the U.S. Congress permitted the states to conduct their presidential elections (or otherwise to choose their Electors) any time in a 34-day period[1] before the first Wednesday of December, which was the day set for the meeting of the Electors of the U.S. president and vice-president (the Electoral College), in their respective states.[2] An election date in November was seen as useful because the harvest would have been completed (important in an agrarian society) and the winter storms would not yet have begun in earnest (a plus in the days before paved roads and snowplows). However, in this arrangement the states that voted later could be influenced by a candidate’s victories in the states that voted earlier, a problem later exacerbated by improved communications via train and telegraph. In close elections, the states that voted last might well determine the outcome.[3] A uniform date for choosing presidential Electors was instituted by the Congress in 1845
