In a Republican primary every candidate is going to come in front of you and say I'm the most conservative guy that ever lived. Goshdarnit, whodidily, I'm conservative. You know what, talk is cheap.

A very good friend of mine spent a fair amount of time doing postmortems and met with a number of the senior folks on the Romney campaign and they spent, what was it, $140, $160 million on data. And this friend of mine, who is a very sharp thinker, asked a series of questions, but the most important one he asked, he said, "What decisions did you make differently because of the data?" And he's coming from the private equity world where he wants to know, OK, and the answer from virtually every single senior Romney person was "nothing."

A friend of mine, a Hispanic entrepreneur asked me a question sometime ago, he said, 'When is the last time you saw a Hispanic panhandler?' I think it's a great question.
