Clinton fatigue (Bill Clinton, that is)

One of the biggest gambles of Hillary Clinton's presidential campaign was putting Bill on the stump. Although the former leader of the free world is a master retail politician and has enjoyed near rock-star status in his post-presidency, there was always the risk that America's collective memory might harken back to not-so-heady days -- think sex scandals, impeachment trials, and dead lawyers. A new Wall Street Journal/NBC News poll suggests that may now be happening. It shows a dramatic swing in Bill's approval rating over the last year. In March 2007, 48 percent of Americans had a positive view of the former prez, while 35 percent had a negative view. Now 45 percent of Americans hold a negative view and 42 percent hold a positive view of the 42nd president. Even stars sometimes fall from the sky.
