A few things could be said for Democratic "opposition " and "support" to bombing.
1st: how many of those 19% are Bushie Oklahoma style types who'll not vote for Hillary in November ? Probably most. How many of the 30% pro-bombing Republicans are likely to back Hillary ? essentially none.
Second, if i recognized Agrabah as the mythical Disney kingdom, saying "uh, no, i see no reason to bomb Aladdin , Jasmine, and Abu" as opposed to "not sure" is reasonable, not ignorant. Minus perhaps 1 or 2 joke respondants (and probably none) thinking "yeah! Napalm Jafar's ass", the yes respondants have no such defense.
Third and most damning, while there is an argument that if one is ignorant of the situation that "not sure" is the best respons--particularly given the genuine threats of ISIL, the Taliban , etc. which arguably warrant some form of non-pacifistic response--thinking "i don't know much about the situation with Agrabah, so no, i don't support the use of bombing until i learn more" is also reasonable indeed. Choosing no vs. Not sure due to ignorance about Agrabah is far FAR more reasonable than any yes respondant, who shamefully just heard a muslim/arabic sounding name and essentially knee-jerk responded "yeah, DIE ALLAHPUKES!!"
Very sad.
