In contrast to past elections, there is little difference between the two parties with regard to the War on Terror this year.
The Republicans criticize President Obama's foreign policy in many areas. However, the War on Terror is not one of them. Obama has not really changed much from President Bush's approach to the War on Terror. He has not closed Guantanamo. He has escalated drone strikes against terrorists. These are all things the Republicans approve of.
If President Obama were not a Democrat, the Democrats might well be criticizing him for his actions. However, since he is a Democrat, the party does not criticize him. This means that they officially support his actions just as the Republicans do.
Therefore, there is no serious disagreement between the parties on this issue.
