DONALD TRUMP: Obama has done 'nothing' for blacks.

On ABC's "This Week," Jon Karl asked Donald Trump about a tweet from last year, where the Republican candidate wrote: "Sadly because Barack Obama has done such a poor job as president, you won't see another black president for generations."

"... I think that he has set a very poor standard, I think that he has set a very low bar," said Trump. "I think that it's a shame for the African-American people.

I'm no Donald Trump fan, but sadly I have to agree that Obama has been such a disaster as President that the memory will cast a shadow on the campaign of the next African-American candidate, no matter how well-qualified he or she may be.
