9th circuit has 29 active judges. Two vacancies when filled by Trump gives 16 DEM appointed judges to 13 GOP judges.
The two oldest on the court are GOP confirmed, birthdays 1934 and 1942. 85 yr old Carlos Bea is TBD, waiting for a Trump approved nominee to bump him to senior status. The 77 yr old needs to be encouraged to move to senior also by 2020 end to give Trump 10 confirmed active judges.
If Trump gets a 2nd term the court could flip.
I am not convinced that Mitch really wants that result. The slow walking of Judges is a joke.
