It could go down as the defining moment of his presidency. Though he was doubted and abandoned by supporters, President Obama was able to twist arms to pass health care reform, signing the bill into law on Tuesday.

We talk with Dean Borg, public radio host and reporter for Iowa Public Radio who was there in 2007 and will be there today to cover Obama’s visit. And we ask presidential historian Richard Norton Smith about the possibilities for President Obama’s lasting legacy.
