Just remember that some of Reagan’s picks didn’t end as well as we’d hoped, so ‘ironclad’ may be a bit of an overstatement. Men by their nature are fallible.
IMHO whoever is giving Trump lists of potential judges is doing a good job. Naturally men are fallible but in the last few decades since Reagan was in office, I think the climate of insanity has been so extreme that potential judges will have shown their true colors in their decisions, writings and opinions.
