My prediction is that the topics of NDAA and drone strikes (some of the most crucial questions of foreign policy) will not even come up, or at very least be avoided like the plague. Why? Because they are areas of vast agreement between both parties and nobody has anything to gain by bringing it up.
If my prediction should not work out, I have a secondary prediction. If NDAA and drone strikes do come up, I predict that there will be no differences in principle over the matter, though there may be minor procedural quibbles.
This is yet another area where there is really no significant difference, except perhaps in degree and minor procedural nuances, between the two candidates.
