For years I have been pounding the point that when voters elect a United States Senator they are "electing" federal judges.
That's because seats on the federal bench are little more than political patronage.
Senators recommend judicial candidates to the president who, usually regardless of party, rubber-stamps the Senators' choices--especially for the United States District [trial] Courts, and often for the United States Court of Appeals (though there the process is more complicated because each of those courts have jurisdiction of district courts in several states).
Yes, Bill Clinton "appointed" Judge Bolton.
But she was recommended by Republican Senator Kyl and voted for by Republican Senator McCain and all other Republicans in the Senate.
With Republicans like those, who needs Democrats to load the federal judiciary with "Living Constitutionalists"?
