NewsHour correspondent Gwen Ifill’s new book, The Breakthrough: Politics and Race in the Age of Obama, was published on Inauguration Day. Ifill, who moderated the vice presidential debate last fall, drew criticism from John McCain supporters when news of her book contract hit the press. Critics assumed she would favor Obama’s camp, but The Breakthrough is “less about Barack Obama’s victory than a generational shift among black politicians and voters, black and white,” says Bob Minzesheimer of USA Today. “Her book is a serious but readable assessment, not a celebration,” he writes. Ifill mentions the debate flap briefly: “I was a hard target to resist — an African-American journalist writing about race could not possibly be capable of thinking bigger thoughts, could she?” An excerpt of the book is available here, from The New York Times.
