You did nothing to illuminate the political makeup of the judges Giuliani picked.
You've described the process. That's all.
Ya, it is non partisan. If highly qualified Republicans don't apply, who are thin on the ground in NYC, and even thinner for those judicial positions (how many Repubican lawyers in NYC want to be family law judges, the ultimate in self inflicted relatively lowly paid professional agony?), then the advisory committee does not recommend them, and they don't get appointed. Simple really.
