E. J. Dionne has an interesting theory on why the typical Republican game plan isn’t working − Because the screwed the pooch on foreign policy last time around.
For the first time since the early 1960s, the Republican Party enters a presidential campaign at a decided disadvantage on foreign policy. Republicans find it hard to get accustomed to the fact that when they pull their favorite political levers — accusations that Democrats are “weak” or Romney’s persistent and false claims that Obama “apologizes” for America — nothing happens.

How did this happen? The primary reason, to borrow a term from science, is negative signaling: By the end of Bush’s second term, the Republicans’ approach to foreign policy was discredited in the eyes of a majority of Americans. The war in Iraq turned out (and this is being quite charitable) much differently than the Bush administration had predicted.
