The minimum number of presidential electors per state is three, according to the National Archives. A state is awarded electors equal to its number of members in Congress.
Each state has two senators, while the number of House representatives is based on a state's population. For the 2016 and 2020 presidential elections, seven states have three electors each: Alaska, Delaware, Montana, North Dakota, South Dakota, Vermont and Wyoming. In addition, the District of Columbia has three. In all, there are 538 members in the Electoral College. A minimum of 270 votes are required to win the presidency. The electors meet in December after the election to formally cast their ballots.
