McCain now polls much better than does Barack Obama on who would be better able to handle the job of commander in chief.
Partly, this explains why McCain and Obama continue to be neck and neck in the polls.
I think Obama was also hurt by some of his earlier statements, too--for example, that he would talk and negotiate with anyone, anywhere (even with Holocaust-denying Iran). I think this raised questions concerning his toughness and naivete, and I think conservatives should continue to hammer Obama on these points.
