American voters elect the President and Vice President of the United States under a complex arrangement of constitutional provisions, federal and state laws, and political party practices known as the electoral college system. Despite occasional close elections, this system has delivered uncontested results in 46 of 50 elections since adoption of the 12th Amendment, effective in 1804. Throughout this period, nevertheless, it has been the subject of persistent criticism and many reform proposals. Related measures fall into two basic categories: those that would eliminate the electoral college and substitute direct popular election of the President and Vice President, and those that would retain the existing system in some form and correct perceived defects.
