What is a likely result of two conservative Supreme Court justices being replaced by two liberal judges?

More liberal rulings

Explanation:

If two conservative Supreme Court justices are replaced with two liberal judges, it would mean that there will be more liberal rulings that conservative ones. For example, if this kind of situation happens, you will begin to see more ruling for affirmative action, and this simply suggests that such Court is more liberal on cases concerning affirmative action.
