Final answer:
A majority voting bloc on the Supreme Court can become a minority voting bloc due to public backlash or when there is a split or insufficient votes to make a required supermajority.
Step-by-step explanation:
A majority voting bloc on the Supreme Court can become a minority voting bloc in several ways. One way is when the public perceives the Court to have gone too far and criticizes its decisions, leading to a loss of power.
For example, Chief Justice Earl Warren and his colleagues faced public backlash during the 1950s for their school desegregation and civil rights decisions.
Another way is when there is a split or insufficient votes to make a required supermajority, resulting in the status quo prevailing. This can happen when there is a 50-50 vote or when there are not enough votes to pass a required threshold.
