WashPost blames “liberal activists,” but can't find any to quote

Ugh. Here's the Post headline, about how Obama's supposedly moving way to slow on judicial nominations:

Obama Criticized as Too Cautious, Slow on Judicial Posts

And the lede:

President Obama has not made significant progress in his plan to infuse federal courts with a new cadre of judges, and liberal activists are beginning to blame his administration for moving too tentatively on what they consider a key priority.

Interesting, right? Liberal activists are really upset with the Obama White House because it's moving too slowly in filling vacancies on the federal bench. Well, that would be interesting if the Post could find any truth to the premise. It can't, but that doesn't stop Micheal Fletcher from typing it up anyway.

In truth, so few judges have been confirmed because, as the Post concedes, Republicans are placing holds on the nominations and doing everything they can to block the confirmation process. To most readers, that would seem to be the story. But the Post wants to spotlight those supposed angry “liberal activists” who are annoyed with Obama re: judges. The problem is, the Post can't find any to quote.

In the entire article, the Post does not include a single quote from any “liberal activists” who “are beginning to blame,” or who have “criticized,” the White House for “moving too tentatively” of judges, or anything remotely like that. The Post just invented that news angle, even though it couldn't substantiate it.
