Today, we learned that Alexander Allan, head of Britain's Joint Intelligence Committee, is on Twitter; Sarah Palin did some tweeting of her own; the White House is very skeptical of a second stimulus; and hospital groups pledged to cut $155 billion of health care costs over 10 years.

We also considered a case against polling; a choice between health care and a second stimulus; what Sotomayor's confirmation process will look like; a former Defense Dept. lawyer's proposal for handling detainees; and President Obama's approval dip in Ohio.

Tomorrow: President Obama attends the G-8 summit in L'Aquila, Italy; Education Secretary Arne Duncan, Homeland Security Secretary Janet Napolitano, and Health and Human Services Secretary Kathleen Sebelius attend a swine flu preparedness summit in Bethesda, Maryland; Vice President Joe Biden hands an event highlighting the stimulus in Cincinnati; and the House Oversight and Government Reform Committee holds a hearing on "thre rise of the Mexican drug cartels and U.S. national security."
