Andrew Breitbart says Barack Obama has a problem, now that he’s opened up the “class warfare” line of argument: The Inconvenient Obama.

Sen. Barack Obama has a problem. And it lives in a hut.

His name is George Hussein Onyango Obama, and he is the 26-year-old half brother of Mr. Obama, the multimillionaire autobiographer who neglected to write that his paternal sibling lives on less than a dollar a month in the outer slums of Nairobi, Kenya.

They have met twice.

Unearthed by Italian Vanity Fair and virtually ignored by the American press, the inconvenient George Obama could emerge as a compelling character in the freshman senator’s carefully edited road-to-the-White-House narrative - especially now that his campaign has unleashed a personal attack on Sen. John McCain’s station in life.
