Obama Camp May Turn To Negative Clinton History

Sen. Hillary Rodham Clinton's victory yesterday in Pennsylvania has only accentuated the quandary that Obama faces: Stay negative and he risks undermining the premise of his candidacy. Stay aloof and he underscores Clinton's argument that he will not be able to beat a "Republican attack machine" sure to greet him this summer....

With Obama clearly favored in North Carolina, even he has called Indiana the "tiebreaker," a state that adjoins Illinois but where Clinton voters hold sway in the working-class towns in the south. In the two weeks leading up to the Indiana primary, a Democratic strategist familiar with the Obama campaign said aides are likely to turn to the controversies of Bill Clinton's White House years -- Hillary Clinton's trading cattle futures, Whitewater and possibly impeachment.
