First of all, where is the same crowd that complained bitterly about the 'liberal press' exploiting Joe the Plumber by telling his true story instead of the fabricated one he and McCain/Palin wanted us to believe.
Second, how is he responsible for her? Isn't she a grown ass woman? Rips is talking like it's some baby in a dumpster that Obama walked by, looked at, and continued walking.
Third, it's very possible that he didn't know. Children of immigrant parents are often taken to the mother country to connect with family overseas. If that's not done the children aren't able to make familial connections with the generations that came before them. Obama saw his father once, when he was 10 years old, and didn't seek out his father's relatives until he was an adult. That's way past the time for him to establish emotional rapport with people and cultures he's never come in contact with. It's just as likely that Obama didn't know his aunt was here. She has children and other nephews and nieces who managed to get her into America and are responsible for her care.
But I know what you guys were going for, a quick, simplistic-but-deadly shot to the throat. Too bad it holds no air. Nice try though. It's cute, but 3 days isn't enough time for this story to develop any traction.
