I do think Donald Trump would be a catastrophic turn in American history.

The Petraeus-Crocker testimony is the kind of short-lived event on which the Administration has relied to shore up support for the war: the 'Mission Accomplished' declaration, the deaths of Uday and Qusay Hussein, Saddam's capture, the transfer of sovereignty, the three rounds of voting, the Plan for Victory, the death of Abu Musab al-Zarqawi. Every new milestone, however illusory, allows the Administration to avoid thinking ahead, to the years when the mistakes of Iraq will continue to haunt the U.S.

The way Donald Trump talks about the problems of black Americans as a kind of separate group who are not part of his audience but he's kind of reaching over his audience or behind his audience to black Americans, saying what have you got to lose? As in you might as well join me because the Democrats haven't done anything for you. But joining me means joining this group that already supports me.

Hillary Clinton said we need to bring back vocational education in high school. We need to support community colleges. We need to make sure that people who are not going to finish college have a job waiting for them and the skills to do the job. These are all - have become fairly standard Democratic policy positions.

When Donald Trump in one speech said I love the poorly educated - which was a remarkable thing to say - he was saying those are my people.

Gingrich was a far more volatile and aggressive individual than Boehner, but the institutional norms of self-restraint, and perhaps even self-interest, have broken down under the pressure of an increasingly abnormal Republican Party.

People in Congress are willing to shut down the entire government or to make it impossible for a Supreme Court nominee to get a hearing or for routine appointments in the executive branch to go unfilled for years because of a hold placed by a senator.
