Paul Krugman: Democrats Being Democrats

On Friday, House Democrats shocked almost everyone by rejecting key provisions needed to complete the Trans-Pacific Partnership, an agreement the White House wants but much of the party doesn’t. On Saturday Hillary Clinton formally began her campaign for president, and surprised most observers with an unapologetically liberal and populist speech.

These are, of course, related events. The Democratic Party is becoming more assertive about its traditional values, a point driven home by Mrs. Clinton’s decision to speak on Roosevelt Island. You could say that Democrats are moving left. But the story is more complicated and interesting than this simple statement can convey.
