As I’ve been noting here, Dems have been trying to turn Mitt Romney’s claim that the payroll tax cut extension is like a “little Band-Aid” into an iconic moment — one capturing how out of touch Romney is with the real financial circumstances of struggling middle class Americans.

Now the DNC is set to raise money off Romney’s remark, going out to its list with a new fundraising appeal based around the sale of mock Romney-brand “Band-Aids” that cost the price of the payroll tax cut extension (alternatively you can chip in whatever size donation you want):

At a recent Republican debate, Mitt Romney declared that President Obama’s proposal to cut taxes for the middle class — tax relief that amounts to $1,500 of extra cash for the typical American family — is nothing more than “temporary little Band-Aids.”

So if you, like Romney, can forgo the money for four months of groceries, seven months of gasoline, or a full year’s electricity bill, we’re pleased to offer a box of Mitt Romney–brand Temporary Little Band-Aids, helpfully priced by Romney himself at $1,500.

This little gag actually masks a serious question for the Obama campaign and Dems, one that they’ll have to resolve sooner or later: How directly should they engage Romney’s personal wealth? Obama/Dem anti-Wall Street rhetoric is growing sharper of late, which means that Romney’s background at Bain Capital will eventually have to become an issue. And as Time magazine reported recently, Romney’s income from investments actually puts him in the class of “millionaire and billionaire” that Obama points to as examples of people unfairly benefitting from the skewed tax code. You’d think Dems would jump on that one, since they can argue that Romney is the last person who should be attacking Obama’s push for tax fairness, given that he’s personally profiting from the current tax system’s unfairness.

But while the DNC has gone after Romney on this front, the Obama campaign has thus far refrained from engaging Romney’s class or wealth.

The “Band-Aid” attack is meant to suggest that Romney’s wealth has rendered him out of touch with middle class concerns, without quite attacking his wealth directly. Eventually we’ll see how far Obama and Dems are willing to take this.
