While the decision to block Merrick Garland is the most egregious example, Republicans have delayed or denied Democratic presidents their nominees to fill federal judgeships for decades.
During the final two years of the Clinton administration, more than 60 judicial nominees were blocked by Republicans. During the first five years of the Obama administration, GOP senators filibustered 36 judicial nominees, as many as had been filibustered in the previous 42 years. President Barrack Obama confirmed the lowest percentage of district and circuit court judges among two-term presidents since 1945.
Stealing the Garland seat, however, represents the pinnacle of Republican obstruction. With the confirmation of Justice Neil Gorsuch, the court further restricted voting rights, undermined worker rights, and upheld the discriminatory Muslim travel ban.
