The legacy of the Bush presidency

In one of his final press conferences yesterday, President Bush patted reporters on the back with one hand while his other hand pounded the podium in defense of his presidential decisions. The mercurial nature of the conference left us wondering, is there any connection between how a president leaves office and their post-presidential legacy? To answer that question we turn to David Eisenhower the director of the Institute of Public Service at the Annenberg School for Communication at the University of Pennsylvania and grandson of President Eisenhower.
