Very interesting data. My first thought is that the percentage of Clinton appointees looks unusually high, but I wonder how much of that is simply due to the retirement of judges who were appointed during prior administrations (Bush, Reagan) plus the fact that W Bush is still early in his second term. In other words, it might make sense that Clinton would have the most judicial appointees since Clinton's was the most recent two-term presidency. Five or six years from now Bush might have the highest number of appointees thanks to his having had the rest of his term to make appointments, plus the retirement of some of the Clinton appointees.
Anyone have any thoughts on this?
