20% of the white democrats who will never vote for a black person under any circumstances

Where did you get this number? There was a rather sloppy analysis that put this at 6% recently, but I hadn't seen 20% anywhere.

Based on the democrat primaries results and specially in the last 15 where Obama was crushed among White democrats by Hillary Clinton. The media polls and despite all its bias are still showing that Obama is not getting more than 60% of Hillary Clinton voters so based on this number I did my calculations and got that approximately 20% of White democrats are not going to vote for him. If you know some democrats you can make your own polling and let me know. I did my own polling among democrats I know here in Massachusetts and I found out that over 20% of them are not going to vote for Obama.
