Final answer:
The U.S. Constitution's Article II, Section 1 and the 12th Amendment establish the electoral vote allocation, based on the total number of U.S. Senators and Representatives. The number of representatives is determined by the state population as per the U.S. Census, outlined in Article I, Section 2 of the U.S. Constitution.
Step-by-step explanation:
The U.S. Constitution does not specify the number of electoral votes for a specific state like Virginia. However, the allocation of electoral votes is determined by the number of Senators and Representatives that each state has in the U.S. Congress, established by Article II, Section 1 and the 12th Amendment. The number of representatives is based on state population as determined by the U.S. Census every ten years, mandated by Article I, Section 2. While the number of representatives may fluctuate, the total number of representatives in Congress has been fixed at 435 since the Permanent Apportionment Act of 1929. Virginia's electoral votes equate to its number of Senators, which is always 2, plus the number of its Representatives, which currently stands at 11, resulting in a total of 13 electoral votes, not 11 as suggested by the question. The census determines if this representation will change.
