Can you tell me about the Presidential election system in America? The electoral college is so confusing!

I can try! It definitely is confusing. The electoral college is a system that was designed back when the United States first began, and information traveled too slowly to inform all the citizens of the latest political news. It allowed states to vote for a representative who would then go to Washington D.C. to vote for the president on the state's behalf. Each state has a certain number of representatives based mostly on the population of the state. For example, California has 53 representatives since they have a higher population. Wyoming only has one representative because it's not as populated as California. In November, citizens place their vote for a representative who will then vote for the president on their behalf.
