Final answer:
Florida and New York have the same number of electoral votes because their population sizes are similar. Therefore, the correct answer is D. Their population sizes are similar.
Step-by-step explanation:
The number of electoral votes granted to each state is based on the total number of representatives and senators that state has in the U.S. Congress. This is determined by the state's population size as measured by the U.S. Census every ten years. The states with larger populations, like Florida and New York, have more electoral votes because they have more representatives in Congress. Therefore, the correct answer is D. Their population sizes are similar.
The Electoral College system involves both the 'winner-take-all' system, used by most states, and the congressional district method used by Maine and Nebraska. This can sometimes lead to a disparity between the popular vote and the Electoral College outcome. Therefore, the correct answer is D. Their population sizes are similar.
