Republicans won in some states with high numbers of people on welfare or food stamps. At least some of those 47%ers voted for Republicans because of social issues.
Also, in the past the argument that "a rising tide lifts all boats" encouraged some voters to support lower taxes on people richer than themselves in the interests of bringing back prosperity. Perhaps such an approach could also work for many of Romney's 47%.
I don’t know if Romney’s statement is wrong or right. I’m just saying that we should be honest about it. If 47% of the voters won’t change their mind based on how things are now, then we have to make some adjustments.
