God knows reality as it is. If it is knowable, then an omniscient God must know it. Satan, men, cameras, etc. cannot know things that God does not know. He is not ignorant of anything knowable.
The reason God does not know all things exhaustively is that some things are inherently unknowable. The future is correctly known as possible vs actual, for e.g. The reason it is not knowable does relate to God choosing to not know something. By creating free moral agents rather than a deterministic universe, the logical outcome is that exhaustive definite foreknowledge is not possible with libertarian free will.
LH and others are not just saying the above, but going to a place few academic Open Theists would. He is saying that there are other knowable things in the past/present (not just future) that God could choose to be ignorant of (even while men and demons know it?!).
This poll may illicit a majority siding with LH (though I could have voted yes based on his wording with the above explanation/qualification, so it may be skewed if someone misunderstands it) on TOL, but if the average non-TOL Open Theist, especially academic ones who are prominent and credible, then he would be in the vast majority.
Besides, we all know the logical fallacies that mitigate against majority or minority being right or wrong. The poll will only reflect a small sample of Enyart influenced types, a tiny subset of those who claim Open Theism beliefs.
Clete and LH are wrong on this one point, but they are vocal.
