FILE - This Sept. 14, 2012 file photo shows a Libyan military guard standing in front of one of the U.S. Consulate's burnt out buildings during the visit of President Mohammed el-Megarif, not shown, to the U.S. Consulate, in Benghazi, Libya. Middle East violence is shaking up a U.S. presidential race that otherwise looks stubbornly stable _ and tight: President Barack Obama holds a tiny edge, Republican Mitt Romney seeks a break-through message, and three debates loom in the campaign's final seven weeks. Republicans and Democrats agree the election is likely to be decided on Obama's jobs-and-economy record, and both campaigns are entering a new campaign week working to shift the focus back to that issue. But foreign policy leaped to forefront of the campaign in recent days, as protestors attacked U.S. diplomats and missions in the Middle East. It's unclear when it will abate.
