How are electoral votes allocated to states?

The current method of allocating electoral votes to states is directly based on how senators and representatives are allocated. Every state has 2 senators and a minimum of 1 representative, and therefore have a minimum of 3 electoral votes. Representatives are based off an odd method. In the constitution it states "The Number of Representatives shall not exceed one for every thirty Thousand." However, as the population grew in 1911 it became necessary to limit the total number of Representatives to 435. The system devised in 1911 to apportion Representatives appropriately is to divide the total population of the United States by 435, then divide the population of each state by the result. There is then a small amount of "fudging" done to get the number of representatives to equal 435. The apportionment is only done every 10 years when the census is taken.
The amount of electoral votes allocated to each state depending on the amount of representatives in the House. Each state has one per representative.
