What do you consider "many?"
Following is a list of all United States federal judges appointed by President George W. Bush during his presidency.
[1] In total Bush appointed two Justices to the Supreme Court of the United States (including one Chief Justice), 61 judges to the United States Courts of Appeals, and 261 judges to the United States district courts.
Supreme Court Justices aside; I was under the impression GW had not filled a lot of vacancies on the benches.
