She is, easily. Her Jamacan dad is lighter than Obama himself let alone his father and that's the only source of her "blackness", her mum is Indian American not black (which of course keeps the melanin topped up), if her mum was white she'd basically look white too - she'd be mixed race over here. she's got both black and white ancestry in Jamacia, the right wing pundits are now making a big deal about how she's not really black nor is she "African American" or an "American descendant of slaves"... in fact apparently her father is descended from one of the biggest slave owners Jamaica had... she's rather mixed in terms of lineage. Obama on the other hand had a black African - Kenyan father.
