To answer, the comment was sarcastic, the point being to criticize the left and their ideology that Obama's skin color somehow makes him special or exempts him from the consequences of his own actions. And you're right; he's half-white, so it makes even less sense.
Anyone who claims a political party doesn't think for themselves. If you consider yourself liberal/democrat or conservative/republican then you do not. I acknowledge I am considered closer to the left. But I take part in no agenda. Few think for themselves on the left or the right. Think about your views. Assess whether you actually think for yourselves. Do your views come from the news any of the stations have a bias. What about religion or your parents? Do your views come from them or do they differ at all? Think about it? If the answer is no, I doubt that it's a coincidence. If these don't apply then you might be a rarity who thinks for themself. It's hard to do. But possible.
Nah, see, your government is just playing possum. Any second now they'll announce they really had trillions of doallars hidden away in a fallout shelter where it is alleged someone had a Scrooge McDuck complex and enjoyed swimming in a pool of money!
