Is it because ah is?

Call me cynical, but I feel my eyebrow rising instinctively when I hear of Obama spending quality time with the ailing grandmother who had been such a support to him, blah blah blah. I wonder if he would have taken so much time off the campaign trail and made such a fuss of it if it was to tend to his black granny. As US African Americans go, he reminds me a little of Steve Martin in The Jerk. This is no criticism, by the way. It may well prove to be a very serendipitous way of getting a non-white male into highest office. If he's half-caste, at least he's half like us...
