Today’s Good News for Romney: Not long ago, Barack Obama held a double-digit advantage over Mitt Romney when it came to foreign policy. Now they’re nearly pulling even, with voters trusting Obama over Romney by only five points, 47-43. That’s an 11-point drop for Obama since September, most likely due to the consulate attacks in Benghazi, Libya, that killed U.S. Ambassador Christopher Stevens and three others. Obama and Romney had a sharp exchange of words on that topic during last week’s town hall debate, and it’s clear that voters are increasingly directing the blame toward Obama. If Romney can continue to depict Obama as weak on international affairs, he may well seize voters’ confidence as a future commander in chief.
