Argument: McCain showed poor judgement in selecting Sarah Palin
"Tribune endorsement: Barack Obama for president". Chicago Tribune. October 17, 2008 - McCain failed in his most important executive decision. Give him credit for choosing a female running mate--but he passed up any number of supremely qualified Republican women who could have served. Having called Obama not ready to lead, McCain chose Alaska Gov. Sarah Palin. His campaign has tried to stage-manage Palin's exposure to the public. But it's clear she is not prepared to step in at a moment's notice and serve as president. McCain put his campaign before his country. Obama chose a more experienced and more thoughtful running mate--he put governing before politicking. Sen. Joe Biden doesn't bring many votes to Obama, but he would help him from day one to lead the country.
"Obama for president". The Atlantic. 4 Nov. 2008 - Negative 2: Leadership style. John McCain is not willfully ignorant and incurious, which is a welcome contrast to George W. Bush. But he has shown during the campaign that he shares Bush's weakness for impulsive, gut-instinct decisions. For Bush: the Iraq war; for McCain, the choice of Sarah Palin and the short-lived "emergency suspension" of his campaign.
Some presidential decisions do require quick, "3 am" instinctual responses. Most do not -- and instead require a willingness to think broadly and dispassionately about the consequences of each alternative, since big decisions have effects that ripple for years. (See: "Iraq war," above.) Like Barack Obama, McCain does not have a record of executive decision-making. Unlike Obama, McCain has provided powerful reasons to doubt his judgment under the kind of pressure that matters most: the pressure to make decisions that are not quick but wise.
"Barack Obama for President". Washington Post. 17 Oct. 2008 - we find no way to square his professed passion for America's national security with his choice of a running mate who, no matter what her other strengths, is not prepared to be commander in chief.
