Here's another story on Maya Soetoro-Ng, Barack Obama's half-sister, who has been vigorously campaigning on his behalf: Obama's Sister Becomes Asian-American Surrogate.
She definitely represents an aspect of Obama's background and identity that makes him unique as a presidential candidate. I'll admit, their relationship and his multicultural upbringing is part of what makes him appealing to me. That said, I really do hope that Obama steps up his efforts to reach out and court the Asian American vote. So far, his sister seems to be doing an okay job.
