According to other readings, Trump has three replacements available on the 9th Circuit at present, but when you look at the chart, evidently when a judge achieves “senior” status, it means that there is going to be a vacancy in the not too distant future. I have also read that there is some unwritten rule that the two Senators in the state affected by a vacancy get to have a say in who is nominated. I just hope that Trump tells the Senators to go take a flying F at a rolling donut.
It’s called ‘Blue Slip’ and McConnell is bidding by it, currently.
