Walker: We Won't Back Down

Two weeks of protests in Wisconsin haven't done a lot to soften Scott Walker: The embattled governor tells Meet the Press today that he's not backing down on his opposition to collective bargaining, reports Politico. "If we do not get these changes and the Senate Democrats don't come back," Walker said, "we're going to be forced to do massive layoffs." Walker had to skip the National Governor's Meeting, Politico notes, but tuned in via teleconference. Elsewhere on the Sunday dial:

• Psy-ops, schpy-ops, says John McCain. "That's been tried on me in the past," he told Meet the Press. "I don't see how it could have affected my positions in any way." Ditto, says Joe Lieberman, calling the story "weird."
• AWOL Wisconsin Democrats are "despicable," Jan Brewer told ABC today. “No one should walk out."
• Potential 2012 rival Haley Barbour had glowing words for President Obama today, calling him "one of the greatest politicians in the history of the United States."
• Mama grizzly Nikki Palin isn't guaranteeing her 2012 endorsement is going to Sarah Palin: " I want them to campaign hard and then when the right time comes I will endorse. But there is no one that I feel like I owe at this time.”
