Doubtless someone else has, but re: the most recent in the wave of federal district court decisions striking down state same-sex marriage bans (summary, link to decision at SCOTUSblog)—
I saw it noted on Twitter that "Most federal judges are ex-prosecutors in their 50s, i.e. cultural conservatives. If they're overwhelmingly rejecting SSM bans, it's over." That was right below a screenshot of the end of the decision, which I will quote at a little more length:
. . . in future generations the label same-sex marriage will be abandoned, to be replaced simply by marriage.
We are a better people than what these laws represent, and it is time to discard them into the ash heap of history.
So I went looking for information about the judge who'd been the most recent to be moved to eloquence on this subject. (Though, I confess, I would have said "onto.") And indeed: John E. Jones III is a Republican appointed by George W. Bush who will be 59 next month. (Though he was a part-time public defender rather than a prosecutor.) He was also the judge on the intelligent design trial, wow, over a decade ago now, how time does fly.
I have no energy to go looking up the rest of the judges now, but, data point.
