I'm getting to be quite the fan of David Limbaugh. About the Lib's plans for Roberts he writes:

Schumer warned that the White House's refusal to turn over every last document, no matter how remote or irrelevant, was "strike one" against the nominee. Robert's unwillingness to answer questions about past and future Supreme Court cases would be "strike two," and the Republicans' Sept. 29 deadline for voting on the nomination could be "strike three."
The tyrannical, would-be Umpire-in-Chief Schumer issued an edict from his minority pulpit declaring there will be "negative consequences" if one or more of these "strikes" accumulate against Roberts.

Elsewhere, Sen. Leahy was unwittingly auditioning for a stand-up comedy gig as he righteously announced, during an interview on Vermont Public Radio, that he will vote against Judge Roberts if he seems likely to pursue an activist philosophy. Leahy said, "I want to find out if he's going to be as active as … people like Justice Scalia and Justice Thomas, who have almost willy-nilly overruled things."
To devout liberals like Leahy, Kennedy and Schumer, an activist Supreme Court judge is one who would roll back precedent established by rampant liberal judicial activism. They know "judicial activism" has a negative connotation, just like "liberal," which they euphemize as "progressive," so they simply turn it completely on its head, accusing its fiercest opponents – Scalia, Thomas, etc. – of being its practitioners.
