With less than three weeks to go before the presidential election, President Obama hit the campaign trail in Iowa on Wednesday, taking a jab at Republican challenger Mitt Romney’s remark during Tuesday’s debate that he had been brought “binders full of women” while picking cabinet members in Massachusetts.

President Obama: “I’ve got to tell you, we don’t have to collect a bunch of binders to find qualified, talented, driven young women, ready to learn and teach in these fields right now.”
