Why would Romney think this is a good idea?

At an event this evening on Univision, Romney referenced "the 100 percent" four times, as in "My campaign is about the 100 percent of America."

What could he possibly be thinking?  This phrasing, awkward on its own, would prompt someone not familiar with the "47%" controversy to look into the situation.  They would of course soon find the tape where he declares his intention to not worry about a near-majority of us.  Those already aware of the tape are reminded of Romney's true feelings every time he says "100 percent".
