There are a lot of long in the tooth judges to be replaced in his second term.
Much as I love his rulings, if Trump is Re-elected and the Republicans hold the Senate, Justice Thomas should be encouraged to retire so his seat can be filled with a much younger Originalist.
Maybe well even get lucky and get to replace Breyer or the Wide Latina.
Also, there are some more Circuit Courts to shore up and a few more to flip.
