President Obama's days of campaigning — at least for himself — are at an end, and for his acceptance speech in Chicago he reached back to some of his vintage oratorical moves, while also offering up shout-outs to his family, staff, volunteers, and not least to Joe "the Happy Warrior" Biden. "Political campaigns can seem small," he admitted. But he cited the ordinary people he had encountered on the campaign trail, and the struggles of people around the world to obtain the right to argue about the fate of their countries, as evidence to the contrary. "That's why elections matter," he said. "It's not small. It's big. It's important."
