Rudy has made statements that go both ways. He praises Roberts and Alito. He also praises J.Ginsberg. [Honest people can have praise for those who they don't agree with personally. RG was praising Ginsburg's personal qualities not her ideology. Even you are not going to claim Hillary/Obama would make as good appointments to the Court as Rudy would.]
But, it's pretty much a given that any of the actual Republicans in the Republican Party Primary Election that we're in would make as good or better appointments than Rudy.
