Assessing Obama's 2011 State of the Union

President Barack Obama went to the battleground state of Wisconsin today to emphasize last night's call for "investment" in clean energy. We hear about the State of the Union address and Republican reaction. On Reporter's Notebook, there was lots of smiling last night on Capitol Hill. We hear the latest research on smiles and how they're perceived by other people.
