National security is a place where the private sector could be helpful because the government is woefully behind the technology curve. But secondly, the bureaucratic processes that have been in place since 9/11 are woefully inadequate as well.

People's ideas and fears can make them small but they cannot make you small. People's prejudices can diminish them but they cannot diminish you. Small-minded people can think they determine your worth. But only you can determine your worth.

I think we ought to ban earmarks. I think we ought to give citizens the opportunity to designate up to 10 percent of their federal income tax toward debt reduction. If we did that, we would reduce our debt by $95 billion a year.
