How does the way the electoral college functions today differ from the framers intention?

A controversial question at best with the Trump and Hillary race this year and the Democrat and Republican issues in our government. The Framers intended for the Popular vote to persuade the electoral college on who to vote for. Today the electoral college functions more like a person who puts a "rubber stamp" on a paper rather than someone who has a voice. We need individuals who have a voice just like those of the past. The Framers of the Constitution created a document that wanted a government that was run by the people not taken over by one person.
