Call it the Bill Clinton conundrum. How can Hillary Clinton's campaign harness the former president's immense political talents in a way that doesn't overshadow his wife or distract from her message? Clinton campaigned vigorously for his wife in her 2008 campaign but was unable to mask his frustration as Barack Obama, then an upstart senator from Illinois, pushed ahead.At one point he derided Obama's claim that he opposed the Iraq war as "the biggest fairy tale I've ever seen". He later seemed to compare Obama to Jesse Jackson, the black civil rights leader who ran for president and twice won the state of Carolina on the strength of African-American votes.The comments were presented to the media as evidence that Clinton was being disrespectful of a black candidate, a charge the former president virulently denied.But even his staunchest supporters admit the outbursts were unhelpful."He was acting like a spouse when his wife was attacked and not a political tactician or a former president," said Matt Bennett, a Democrat strategist.Another danger is that the famous Bill Clinton charm steals the spotlight from his wife.For now the strategy appears to be that Hillary will travel on her own for the beginning of the campaign, and Bill will be "a backstage adviser" until closer to the election.If Hillary Clinton faces any serious opposition in the Democratic primary he may join the fray but he will certainly be at her side to make the case against the Republicans in November...
