Almost a heartbeat away

The picture presented in Game Change of Palin's emergence as national phenomenon — and the real Palin behind her public persona — is often startling and sometimes shocking. The scantness of the vetting she received before being placed on the Republican ticket. Her substantive deficiencies, even more dramatic than those that had previously been reported: her lack of understanding about why there are two Koreas, her ignorance about the function of the Federal Reserve, her belief that Saddam Hussein was responsible for 9/11. The fact that, at her lowest moments during preparation for her debate against Joe Biden, some senior McCain aides worried that she was mentally unstable. And, ultimately, their fears that she wasn't up to the job of being Vice President.
