He understands that just based on the quote about the 47% who will "vote for Obama" no matter what. But he also broadened it to include the returning vets and the folks in nursing homes, etc. I.e., Rmoney was trying to lump too many groups in his false assertion by using this same % to indicate people who "didn't pay taxes".

Of course he forgot to include himself too.

he's lumping a greater number than 47 percent in to the people he says will vote for Obama no matter what. This 47 percent isn't just Democrats is Indies and Republicans.

This is the point that is being missed.

“There are 47 percent of the people who will vote for the president no matter what. All right, there are 47 percent who are with him, who are dependent upon government, who believe that they are victims, who believe the government has a responsibility to care for them, who believe that they are entitled to health care, to food, to housing, to you-name-it,” Romney said, according to the Mother Jones transcript. “That that’s an entitlement. And the government should give it to them. And they will vote for this president no matter what … These are people who pay no income tax.”
