In 1804 the 12th amendment changed the way the united states

The Twelfth Amendment to the United States Constitution changed the way the United States President is elected. Before, President and Vice president could belong to different parties hindering manageability. In order to cure the flaws of that electoral system, The Twelfth Amendment was introduced in 1804. The most important characteristic of the 12th Amendment is that instead of casting two votes for President, each elector must pick a President AND a Vice President.  This makes certain that the President be paired with his running Vice President.  The Electoral College is composed of representatives from each state and Washington DC and the biggest states will have more representatives, which are called “electors.”  These electors give all their votes to the Presidential candidate that wins the popular vote in each state. The Electoral College is unique to the United States.

With this system, every state, even the small ones, have at least three representatives in the Electoral College.  This means that every state at least has some say in electing the next President .

Explanation:

The 12th Amendment of the US Constitution provided the procedure of the election of the President and Vice President of the US. 

The Amendment came after the experiences of the 1796 and 1800 presidential elections. With the amendment, the number of candidates was lowered, established that the Senate would hold a contingent election for vice president if there was no majority winner and also provided that no individual that was ineligible to be president would be eligible to be vice president.

But the main change was that each member of the electoral college is required to cast one electoral vote for president and one electoral vote for vice president and if there is no candidate wins the majority, the House of Representatives would hold a contingent election.
