They could have changed the rules when they got the majority and they could have pushed for alternatives with some random ideas off the top of my head a.) just putting their appointed justice on the court while Obama was still President since the constitution does not specifically say approval just consent so with the anything goes interpretation of original intent that the current supreme court uses why not, b.) packing the court after they got the majority, c.) deciding to make term limits for supreme court justices - the forever a justice is not in the constitution. It like the current situation where one senator Tuberville can block the mass appointment of military leadership, they could change the rules or do it one by one but the leadership is too afraid of changing the way things have always worked around here.
