Note that the probability in general that an electoral system using something like the electoral college increases the chance for everyone that they will be the deciding vote assuming that no voting area is extremely in the direction of one candidate. To see this with a small example, consider the toy example of 9 people with three states each of three people with an election for two candidates.. If the election is by popular vote then the only way your vote matters is if exactly four of the people vote for one candidate and exactly four vote for the other. But, if you use the states then your vote breaks a tie whenever the other two states disagree and your state has a 1-1 for the other two voters. That’s a much larger set of circumstances. This applies in general although the math to show it becomes a bit uglier when one has many different states of different sizes.
