From Iron Knee at Political Irony:
There is a good argument to be made that the Republicans unpacked the Supreme Court by refusing to consider Merrick Garland, bringing the size of the court down to 8 seats in 2016. This then allowed them to repack the court during Donald Trump’s administration, appointing three justices.
This doesn’t include hundreds of other federal court judge appointments that were delayed during Obama’s administration, but were then rushed through during the Trump administration, stacking the federal court system with staunch conservatives who are barely qualified for the job.
Even worse, the media seems to be ignoring that Republicans have been doing lots of court packing with little notice at the state level.
