From the left of course.
The AP has it:
WASHINGTON - Anti-war activists at a liberal gathering booed Sen. Hillary Rodham Clinton on Tuesday for opposing a set date for pulling U.S. troops from Iraq. Facing down the jeers, Clinton said Democrats need to have "a difficult conversation" about the war.
Another potential presidential candidate, Sen. John Kerry, spoke to the group later in the day and offered an emphatically anti-war appeal.
Sounds like Kerry, never missing an opportunity, outflanked Hillary to the left:
Kerry, who was widely criticized as the party's standard-bearer in 2004 for being too cautious in his criticism of the war, said Tuesday that politicians "cannot have it both ways."
In remarks that could have been aimed at Clinton, Kerry said: "It's not enough to argue with the logistics or to argue about the details. ... It is essential to acknowledge that the war itself was a mistake. ... It was wrong, and I was wrong to vote for that Iraqi war resolution."
The question isn't about the war, it's about what makes them feel good.
