In politics, Hillary Clinton speaks for the Clinton family now, and aside from her campaign debt, she has no real difficulty supporting Barack Obama privately and publicly.
But Bill Clinton has a beef. A Democrat who has spoken directly to Clinton about his feelings said that the former president remains "miffed" for two reasons. One is that he feels that Obama's candidacy was essentially an anti-Clinton candidacy; that Obama ran against Clinton's presidential record at times, implying that it was timeworn, divisive, and damaging to the party while adopting policy positions that seemed to flow directly from the Clinton oeuvre. Why should Clinton embrace a guy who spent the past twelve months bashing him and his accomplishments?
Two: Clinton is convinced that the Obama campaign went out of its way to portray the former president as a racist. Clinton wants a private meeting with Obama to sort these things out; he has reconciled himself to the reality of Obama's nomination and does not want to sit on the sidelines.
