Judging from her interview on “The Daily Show” Thursday, you wouldn’t be able to tell that Nancy Pelosi is one of the most powerful figures in Washington. Throughout her discussion with Jon Stewart, the House minority leader passed the buck for the government’s failures and acted as if she is completely removed from any position of responsibility. “I don’t know,” Pelosi said when asked by Stewart why it was so hard for the government to “get a company to execute” something like building HealthCare.Gov “competently?” “Well, let me get the House minority leader here, I can ask her, hold on,” Stewart said through laughter, mocking her answer. “Wait. What do you mean you don’t know? How do you not know?” “It’s not my responsibility,” Pelosi said.
