Newt Gingrich has a restless and outsized intelligence that is tragically unleavened by any kind of critical sensibility.

• The United States established itself as a trustworthy new nation in its first two decades after the Revolutionary War by paying its debts, even when many in the country believed it had no obligation to do so. Alexander Hamilton, the founder of this newspaper, insisted on it.
• The idea that the rest of the world was somehow being held hostage by the Arab-Israeli conflict once had a minimal basis in reality. In the first 20 years of Israel's existence, every Arab country was in an active state of war with the Jewish state.
• Hurtling the Pentagon into an unprecedented budgetary meltdown is horrifically irresponsible. Obama doesn't care. This is war - not against the Taliban, but war against the GOP. He has Republicans on the ropes, and that's a victory he savors and desires - unlike Afghanistan, where he seems only to want to turn tail.
• Romney is right that the Obama vision is too centered on government. But his is too centered on the promotion of business and wealth creation at the expense of everything else.
• Your race and gender don't change, but you can choose to change your political affiliation at will.
• Pop culture is a reflection of social change, not a cause of social change.
• All non-incumbent campaigns promise hope and change, but Obama took the promise to a new level of absurdity. He suggested that a vote for him would literally transform the Earth.
• It has never made any sense to argue that, unique among the people of the world, Arabs are more concerned on a day-to-day basis about the treatment of people they don't know than they are about how they're going to put food on their own tables, or whether their sons will ever find a job.
• The problem is that borrowing money to pay back more borrowed money that will oblige you in the future to borrow even more money doesn't sound kosher. Because it isn't.
• The attack on ObamaCare was that Congress does not have the power under the Commerce Clause to force a private citizen into a private contractual relationship. If such a thing is permitted to stand, the anti-ObamaCare forces argue, there will be no limit to Congress's power in the future.
