If Barrack Obama knew what every member of his extended family was up to at all times, he wouldn't be needing to run for President. He'd already be God.

If he helped his aunt stay in the country illegally or if his campaign took money from her while knowing she was a foreign national, this would be an issue. But there's no evidence that either occurred, so it's irrelevant. That she happens to be related to him is coincidental.

Even the McCain campaign is calling this a family matter and leaving it alone. Take a clue from them.
