The economic case for insuring undocumented immigrants.
Politically, insuring illegals would be disastrous. That's why no one in Congress or the White House is proposing it. Even the Center for American Progress, which generally agrees with the administration on health care issues, argues that health care reform and immigration reform should be separate: First get illegal immigrants documented, then insure them. But if Obama wants to make the purely economic case for health care reform, it seems odd to reject a potential source of savings.
