Final answer:
The Electoral College enables major parties to shift blame through the role of third parties and by criticizing the party in power.
Step-by-step explanation:
The Electoral College (EC) enables the major parties to shift blame in a few ways. One way is through the role of third parties, which often serve as spoilers and take votes away from one of the major parties, potentially causing the other party to win. This allows the major party to shift blame to the third party for their loss. Another way is through criticizing the policies and beliefs of the party in power. The party that is not in power often criticizes the party in power to sway public opinion and garner support for their own candidate or platform.
