Presidential politics is a tough business, especially for incumbents who fail to make the cut as re-elected Commanders in Chief. Jimmy Carter, who rode the wave of anti-Watergate sentiment all the way to the White House in 1976, was ousted in landslide to Ronald Reagan in 1980, courtesy of the economic malaise that engulfed the nation during the late 1970s. George Herbert Walker Bush, elected in a rout of Michael Dukakis in 1988, failed in his re-election efforts as economic woes — and Ross Perot’s third-party candidacy — sealed his fate.
