The framers made the electoral college system to reduce the impact of populous states and raise the impact of less populous states so everyone gets an equal voice. Without it, you would get heavily populated states like New York and California dictating policy for the rest of the country.
And what we now have is low population states thwarting the will of the majority due to their numbers in the senate. It’s a major power imbalance. Every time a Democrat is elected President Texas legislators threaten to secede. At some point California and others will also start threatening this unless the power structure is rebalanced.
