we are joined now by katrina vanden heuvel, editor and publisher of "the nation," america's oldest weeklyine. again, "the nation" is celebrating its 150th anniversary with a quintuple-length, blockbuster edition of the magazine. welcome. happy birthday. katrina: thank you, amy. this is daunting, and it is something to survive, if you think, three centuries. we were founded in this great city by abolitionists committed to and -- to end slavery, but also eric writes about the contested meaning of freedom, and the founders believed in it as a universal birthright, but boy, has it been contested, and we can see it is still a battle. the words you read from the new deal era, think about how resonant those are -- may we save the republic from despair. it is those echoes, the fact that history remains present alive. this is about the past, present and future, and another 150 years is what we are committed to. juan: in an age where a magazine is lucky to survive 10 years, or counts themselves among the big ones if it survives 20 or 30 how has "the nation --"the nation" managed to survive for 150
