Today, Nokia and Siemens defended their contract to provide communications (along with filtering mechanisms) to Iran; the Supreme Court upheld Section 5 of the Voting Rights Act; Gov. Mark Sanford is missing, though his staff says he's taking some R and R; and two Metro trains collided in DC.

We also considered the demography of the Obama administration; Medicare's efficiency as the key to a public health insurance plan; the Voting Rights Act ruling; that the ball is now in Congress's court; whether a new fight looms; what opponents of health reform will say; whether Iran's political elite are manipulating the protesters; the new meaning of Mousavi; and Obama's gay jokes.

Tomorrow: President Obama meets with the president of Chile and holds a press conference in the Rose Garden; Vice President Joe Biden chairs a meeting of the White House Task Force on Middle Class Familites on manufacturing; the House Education and Labor and Energy and Commerce Committees examine health care reform.
