The problem is the quick response by the R's was ineffective. They did not come out directly and talk to this particular issue. Most of the masses will already have in their heads that Bush was saying Obama wants to appease, he's already answered it.Perhaps that may be what he wanted, but if you pay attention, it makes him look petty, and scripted, at best, at worst, it's scary how defensive he got over a general comment regarding appeasement.
With that and a bit of positive media help he's well on his way to "winning" this particular encounter.
Had the R's immediately come out with, "Why so sensitive? Too much truth?" it would have been an R victory. It was a bit of a risk, but he's already past the risky portion.
