The lack of the possibility of filibustering will only matter to the Republicans if and when the RATs both control the White House and have a majority in the Senate. There's a good chance those two things will not happen together again for many years.
Plus, Republicans have not been in the habit of filibustering judicial appointments. We could do it from now on, as an answer to the RATs' filibustering. But don't you think there's a good chance we won't?
