Basically, I am a night owl. My wife is an early bird, so she goes to bed around 9:30, and my kids are in bed about 8. So, if I am home, I will usually start writing about 9:30 and go till about 12:30 or 1:30, depending on what my energy level is.

America, we weaken our ties when we allow our political dialogue to become so corrosive that people of good character aren't even willing to enter into public service; so coarse with rancor that Americans with whom we disagree are seen not just as misguided but as malevolent. We weaken those ties when we define some of us as more American than others, when we write off the whole system as inevitably corrupt, and when we sit back and blame the leaders we elect without examining our own role in electing them.

But let me perfectly clear, because I know you'll hear the same old claims that rolling back these tax breaks means a massive tax increase on the American people: if your family earns less than $250,000 a year, you will not see your taxes increased a single dime. I repeat: not one single dime.

We cannot drill our way out of our addiction to oil.
