Recently, but not nearly surprisingly, Senator Dick Durban (D. Il.) made an issue of Roberts' Catholicism, but not really according to the Senator.
Wendy Long, of Bench Memos, quotes Judge Robert Bork on the relevance of the question of whether a judge's faith would matter were he not Catholic.
[We know the Democrats' scrutiny is mostly a pretext for abortion/Roe.] For a judge critical of Roe, the decision to overturn it could so easily (and reasonably) rest on the case's illogical reasoning that someone like Roberts need not be inspired by his faith to be activist.
