In today's Washington Post, EJ Dionne assesses the potential damage that Barack Obama and Hillary Clinton are inflicting on one another. And he suggests that Clinton's campaign "needs to examine not what this fight has done to Obama but what it is doing to her.

"For all Democrats," writes Dionne, "the worst thing that has happened since January is the tarnishing of the Clinton brand. Clinton haters: Don't laugh. The truth is that when this whole thing began, the vast majority of Democrats -- including Obama supporters -- and a fair number of independents had largely positive views of Bill Clinton's record and Hillary Clinton's merits."

Now, "much of this has been lost," says Dionne. "Bill Clinton's approach to the South Carolina primary, the Clinton campaign's effort to ignore everything it once said about the irrelevance of the Florida and Michigan primaries, Hillary Clinton's willingness to say (or imply) that John McCain is better prepared to be president than Obama -- all this and more have created a ferocious backlash against the Clintons."
