Arianna: White House Must Draw Line In The Sand On Health Care (VIDEO)

Arianna appeared on "Countdown with Keith Olbermann" tonight to discuss some of the myths currently circulating about the plan to reform health care. "The truth is," she told Olbermann, "that whenever you leave a vacuum, as the administration has left, you leave the door open for all these lies, all these crazy allegations to actually gain ground."

More broadly, Arianna argued that the spread of health care misinformation should "demonstrate to the administration that they need to draw some lines in the sand, they need to define what they are asking the public to fight for, or vote for, or believe in." She noted that, just today, White House Press Secretary Robert Gibbs said that the administration has not yet given up on recruiting more Republicans -- "this delusion of bipartisanship."

"When are they going to give up on that?" she asked. "Are they going to give up on that when those who want real health care reform are down to 30 percent or under? Because the trend is clear and the trend is downward. And it's not just in these polls that we see this happening. There was an article in the New York Times about the grassroots -- you know, the formidable Obama machine that we all marveled over during the campaign is not coming to the fore anymore, because what are you asking them to fight for? What are you asking people to go and knock doors for? They don't know. The Obama plan has not been defined. It needs to be defined."
