Equally, a loss would not have been opposition to the war.
Right?
Also, I like this "majority did not vote for him" angle. Again, we can use this same principle and say even more people voted against Blair's, Howard's and Bush's opponents, who were mostly or all against the war, than Blair, Howard and Bush themselves.
But so what?
At the end of the day, it simply depends on which way people want to spin the election results in line with their own biases. Give these election results as little or as much significance as you want. It's all moot. The results are in. The people have spoken. Time to move on.
