Kerry should emulate Humphrey, and now

In the last week of the 1968 presidential race, LBJ announced a halt on bombing of North Vietnam; at the same time, Humphrey came out more strongly against the current conduct of the war, and to a degree, even the war itself.
Humphrey significantly closed the gap in Nixon, but while it was not too little, it was in fact too late.
Kerry needs to take note.
Rather than blathering about intending to get most if not all troops out of Iraq within four years, he needs to talk about getting all U.S. troops out as soon as reasonably feasible.
