None, but many presidents have varied the total number of judges on the court.
I would love for a conservative president to appoint 3 to 5 die hard conservatives to the court.
Then I would either impeach or if that’s not possible re-assign every liberal judge in the US to a 1 square foot piece of meaningless dirt and cut their salaries and benefits to $1. Then appoint conservative replacements for all of them that will promptly right all the wrongs that have been perpetrated by liberals on this country.
Then I would start rounding up the domestic traitors and start charging and jailing them.
Dream big! ;-)
