He's just not the same Bubba.
Hillary Clinton's husband is still brilliant, still passionate and still a magnificent campaigner. But people who have known him and observers who have watched Bill Clinton for decades say he's lost at least half a step.
Think of him like Michael Jordan - only the past-his-prime version, playing for the Washington Wizards.
More than one acquaintance used the same words: "He's just not the same."
Colleagues point to a slew of potential reasons for Bubba stepping in it so often, including psychological and medical.
Some think he's not up to speed with the instant news world of the 21st century and spending too much time with wealthy, globe-trotting pals.
