"Nothing could provide any "assurances that there won’t be another David Souter next time".
When I go to the horse races, I try to pick the ones with the best chance of winning based on their prior track records. I don't gamble on an unproven horse. Nothing is assured when it comes to judges, but some candidates are more assuring than others.
I do not go to horse races at all. And I find it rather amusing that many people are as apoplectic as if GWB nominated hillary. He hasn't.
