A more acurate quote
"And what's important to me is to have a very intelligent, very honest, very good lawyer on the court. And [John Roberts] fits that category, in the same way Justice Ginsburg fit that category. I mean, she was -- she maybe came at it from a very different political background, very qualified lawyer, very smart person. Lots of Republicans supported her." Rudy Giuliani ["Hannity & Colmes", Fox News Network, 7/20/05
Again, the comparisons to Ginsburg were made during a time when Rudy was stumping for Roberts and attempting to show the Democrats' double standard on SCOTUS nominees. He was working within the political arena for President Bush's nominee.
The fact that this point is lost on you is indicative of your political ignorance.
