Why are most white guys less interested in black women?

So there was a POLL, most white guys voted they prefer white women the most

Second they voted was Asian women. The votes for Asian was still high, but white women received the most votes.

Third was Hispanic. Black received the lowest to almost 0 votes

Why is this? Asian women are more hard to even date due to cultural or other issues.

White and black still share a very similar culture.
