With some form of conflict between Israel and a variety of foes looking increasingly likely before the year is out, I predict victory for... Hillary Clinton, regardless of the outcome for the actual combatants.
If mosque boy fails to forcefully support Israel in a conflict, especially in the event that rocket attacks by Hezbollah or Hamas cause significant civilian casualties, Hilary could resign on this point of principle before the November elections, and thus avoid being tarred as disloyally kicking Obama while he's down by resigning to launch a challenge to him in the wake of the looming mid-term meltdown.
While this would be the most promising scenario from the point of view of a potential presidential bid, the other possibilities are hardly much worse. Robust US backing for Israel,while it wouldn't hurt Obama, would do nothing to save Democrats in the mid-terms; and it would give Hilary plenty of positive exposure as a tough supporter of Israel against common terrorist enemies. A third option, a bout of high-profile shuttle diplomacy leading to an end to fighting, would also enhance her credentials. In either of the latter two cases, thus bolstered, she could then leave the administration anyway next year if Obama's prospects for 2012 continue to deteriorate.
