Answer:
Today, all but two states (Maine and Nebraska) award all their electoral votes to the single candidate with the most votes statewide (the so-called "winner-take-all" system).
Step-by-step explanation:
After the 1800 election resulted in a deadlock, the Twelfth Amendment was ratified in 1804. It changed the election procedure so that instead of casting two votes of the same type, electors would make an explicit choice for president and vice president.
