Commie heartache.

(Briefing Room) — President Obama’s communications czar sought to soothe frustrated liberals Friday, telling them Obama needs their support to win reelection.

White House communications director Dan Pfeiffer faced a grilling during an appearance at the Netroots Nation conference, a gathering of liberal bloggers and activists meeting this year in Minneapolis.

Pfeiffer faced tough questions from Kaili Joy Gray, an associate editor for the liberal blog Daily Kos, who often reacted to the communications director’s answers to questions with an audible sigh or a skeptical, elongated “OK.

(“Frankly, we’re all a little sick of hearing about that one,” Gray said of Pfeiffer’s mentions of the Lilly Ledbetter Fair Pay Act.) Hecklers sometimes interjected during the Q-and-A, voicing their skepticism toward Pfeiffer and accusing him of being evasive in his answers.

Pfeiffer admitted that the administration has been “frustrated” with its critics on the left, but pleaded for their support heading into 2012.

“We can either work together and finish that work that we started in 2008 or we can be relegated back to the sidelines and see what a Republican president . . . does to this country,” he said at the event, which was streamed online.

Pfeiffer said that Obama is “absolutely” counting on his liberal base to turn out in 2012.
