Bolton cramthrough stymied?

Steve Clemons says "Senator Hagel has stated unambiguously that he is now 'undecided' on John Bolton."

I'm not quite sure how to read this, but it could be that Bush has miscalculated in pushing the Bolton confirmation again precisely when his visibility is heightened due to the mid-east conflagration and Republicans are wary about voter backlash in the upcoming elections. While Hagel isn't facing reelection himself, he is campaigning for Republicans in Nebraska.
