I think the phrase was intended to contrast the half with the 100%, not imply anything negative as to Barry-O’s racial makeup,

I read it like saying, “He may be only half-black, but he’s 100% Marxist.”

I note that the “he’s not ‘black’ enough argument has been a prior point levvied against Barry-O from some on the Left, and if that’s a remark at all tinged with racism, it is a “reverse” sort of racism of a “black on half-white” nature, not the white-on-black variety that is the Left’s usual favorite. The bottom line on that, though, is that Barry-O’s being half-black has been fronted as a strike against Obama by some on the Left, not by Conservatives.

So, I’d reword the phrase something like this:
“Being half-black may make him ‘not black enough’ for some Americans, but being 100% Marxist makes him too far left for any Americans.”

See my Post # 51. I agree with you. I think it’s a rhetorical device. But don’t point that out to Plain ole American. To in any way comment on the style of the story, as opposed to its content, is to leave yourself open to attack.

“Being half-black may make him ‘not black enough’ for some Americans, but being 100% Marxist makes him too far left for any Americans.”

That's good. I like that.
