In a fresh postmortem on Hillary Rodham Clinton's presidential bid, newly published staff memos and e-mails reveal a campaign hobbled by internal rivalries, faulty planning, bloated spending - and perhaps most important, Clinton's own failure to make the hard decisions. Clinton offered herself to voters as a hyper-competent executive ready to be president from day one. But atop her own campaign, she was a hesitant leader, who allowed bitter infighting to fester among staffers over whether to go negative against Barack Obama, according to the Atlantic magazine. The most bare-knuckled lines of attack came from Clinton's chief strategist, Mark Penn, who urged Clinton to highlight Obama's "lack of American roots" due to his upbringing in Indonesia and Hawaii - saying he could only win if he faced Attila the Hun.
