When are Americans going to turn decisively away from the Iraq War?

[cali]

And what are the implications when they do so? I feel that Americans are right on the verge of turning from tentative support of the war to outright hostility against bushco. Just over half of Americans already believe going into Iraq was a mistake. A larger number believes we need to stay there until the "job is done." I don't see the elections being anything but more fuel added to the fire. What happens when the tide of public opinion turns? Does bushco approval rating sink into the low forties? What does this portend for his agenda? Does it give dems in the House and Senate more leeway to block his agenda? Will voters take it out on repubs in the '06 election cycle?
