Romney agrees with Obama on key part of healthcare

When the Supreme Court upheld President Barack Obama's healthcare law as constitutional last week, it gave a little something to his Republican foes: The court declared that the fee charged to most Americans who refuse to buy health insurance amounts to a tax - and not a penalty, as Obama says.

In the heat of a presidential campaign, that's a key distinction. Since Thursday's ruling, many Republicans have accused Obama of imposing a massive "tax" through his healthcare law, saying it disproves the president's claim that he has not raised taxes on the middle class.
