What's the Matter with New Jersey?

Now that the Democratic Primaries are over in a competitive sense, I was interested to look at the exit polling numbers. My goal was to find the most racist states, based on the percent of the white vote that went for Obama. I relied on exit polls from the MSNBC website. I tried to leave aside states in which John Edwards garnered a significant percentage, and some states were not included because voting results by race were not included in the exit polls. (And some states may have been left out because I didn't do a completely thorough analysis - sorry.)
So, here is a list of the states in which Obama won the smallest percentage of the white vote:
Arkansas 16%
Alabama 25%
Mississippi 26%
Tennessee 26% (Edwards got 6% of white voters)
Louisiana 30%
New Jersey 31%
Ohio 34%
Pennsylvania 37%
New York 37%
Indiana 40%
The top (or bottom) five are southern states, former Confederacy states if you want to say that. Outside of this region, the state in which white people votes least for Obama was my own home state of New Jersey, a state that is supposed to be educated, liberal and presumably enlightened.
I am very disappointed. I would like an explanation for this. In Georgia (43%), Texas (44%) and Virginia (52%) whites voted in greater numbers for Obama than they did in New Jersey.
Maybe in NJ Obama received a lower percentage of the black vote also. Well, in NJ Obama did receive a lower percentage of the black vote (82%) than he did in Georgia (88%), Texas (84%) and Virginia (90%), Alabama (84%), Mississippi (92%), Louisiana (86%), Ohio (87%) and Pennsylvania (90%) and Missour (84%) as well as other states. So maybe people in NJ rather than being the most racist outside the south, just love Hillary Clinton.
Other states in which Obama did poorly among black voters were New York (61% - a strong Hillary state obviously), Arkansas (74% - another Clinton state where Obama did poorly in all categories), and finally California (78%) and Connecticut (74%), two states in which he did very well among white voters, interestingly.
Anyway, I don't know what my conclusion is, but
I found all this to be somewhat interesting, as well as very uncomfortable, all this focus on race and racial voting patterns.
Questions: Why did Obama do well with white voters in CA, CT, VA, and to some extent GA? Why did he do so poorly with white voters in NJ? Why did he do so dramatically poorly with black voters in New York (61%)?
