In it, but not of it. TPM DC
On national security overall, the Republicans have a statistically insignificant edge of 43%-41% over the Dems, and it's a dead-even tie of 41%-41% for the War on Terror. The GOP maintains a 53%-35% advantage on "ensuring a strong military," but the Dems have a 52%-35% lead on "foreign policy," a 44%-32% lead on Afghanistan, and a 47%-37% lead on Iraq.
The Democratic gap on defense originated in large part because the Dems launched a failed war in Southeast Asia, then collapsed in partisan infighting over it. The GOP could perhaps be suffering from the fact that they launched two mismanaged wars in the Muslim world, and now stand resolutely by to declare that nothing was wrong.
