It’s strange to remember how bitterly divisive the 2008 Democratic presidential primary battle was. Hillary Clinton’s and Barack Obama’s platforms and ideological positioning were awfully similar. And on the chief difference between them — Obama’s less hawkish foreign policy — the victor wiped away that distinction by appointing Clinton as secretary of state. Now Clinton has announced her candidacy and is poised to coast through the 2016 Democratic primaries as her party’s prohibitive favorite. Would a Clinton presidency be essentially a third Obama term?
