MEGAN MCARDLE: Is Demography Destiny? “It was a close election in which Obama lost states that he carried in 2012. The Democratic bench is very weak–the current leading candidates to succeed Obama, Hillary Clinton and Joe Biden, will be 69 and 74 in 2016. And Obama is going to have to preside over some very, very tough choices. We can’t borrow a trillion dollars a year for another four years. Nor can we get all the money from Republican constituencies; they just don’t have enough of the stuff. Whoever’s ox Obama chooses to gore will probably be a considerably less enthusiastic coalition member come 2016.”
