Final answer:
Changes in the electoral college from 1960-1992 were influenced by political party realignment and changes in the voting system, including the introduction of popular vote determining electors.
Step-by-step explanation:
From 1960 to 1992, there were changes in the electoral college due to a variety of factors. One major factor was the realignment of political parties, where socio-economic divisions played a role in voters' party preferences. The Democratic Party won five consecutive presidential elections during this period, building a political machine that dominated Congress. Additionally, there were changes in the voting system, such as the introduction of popular vote determining electors in some states. These changes influenced the electoral college outcomes.
