Of particular ridicule is this portion:
... and his sky-high ratings among African-Americans make some of his positions appear a bit more popular overall than they actually are.
I would like to say that in the article he goes into some analysis of the numbers an explains his statement. I can't do that though, he doesn't analyze anything, he just spits out statistics with no real statistical argument.
Either way I can read the original statement and not think it is racist.
Many black's in America (do I really have to say African-Americans) rate Obama highly. One can't really assert that this is the same as agreeing with his positions, e.g. loving the man is not the same as loving his positions.
However the fool (York) never really makes this connection and presents statistics about how blacks and whites rate Obama's performance differently.
To defend himself against the charges of racism from the "usual suspects on the left" he cites that statistics can be misleading and the poll statistics are interesting and his critics should take time to analyze them - something he didn't bother to do.
From his article, I don't think he is a racist, I just think he is a bit stupid.
