From the article:
Obama's call for change makes things very difficult for Hillary. Should she, as Gore tried to do, now distance herself from her husband? Bill's role in her campaign was tentative at first, but Hillary has had to call on the genie of his charm. Recently the bumper stickers have grown more confident: " Vote Hill, Get Bill". Hasn't he been her greatest advocate? Yet my favourite quote from Iowa was the voter who said of Bill's praise of Hillary: "It's like my mom saying how great I am."
Bill Clinton reportedly said to his friend the journalist Sidney Blumenthal that " trashing me is fine, if it helps Hillary". This may be the moment for Hillary to test whether she can survive on her own. In New Hampshire, Hillary is just ahead in the polls. She must show herself as more than a political construct or a marriage. Hillary Clinton needs to be bigger than the sum of her history.
