What is the “nuclear option” and how does it apply to judicial nominees?

What will be an ideal response?

The nuclear option is eliminating the filibuster in the Senate. Because of a series of disputes over blocking Obama’s judicial nominees in the Senate, the filibuster was ended for executive branch and judicial nominations only. The filibuster is still permitted for Supreme Court nominees. This resulted in far fewer of Obama’s judicial nominees being blocked by the Senate, at least when it was under Democratic control.
