No, it's almost definitely the 60/40 split I described if not even more unfavorable to Israel. If you read my post carefully it wasn't about support for Israel vs. support for Palestine, it was about support for Israel to be running US foreign policy in that respect. So like I said, I find it unlikely that even all the people who support Israel support them running our foreign policy, it's a very safe bet that almost all those people who are not supporters of Israel/don't care/whatever would not like them running our foreign policy.
This isn't really an Israel/Palestine thing, this was a 'Nebor saying something insane and unsupportable' thing.
