What specifically did he do since you are so certain he did everything?  Merrick Garland didn't get the consent of the Senate and if Hillary would have won he probably would have been replaced by one of her nominees.

Neil Gorsuch will forever be known as a Donald Trump Supreme Court Justice.  You had best get used to it or foreve live in a state of denial.
