Michelle Obama is certainly not someone I consider attractive. If Barack Hussein Obama loved America and loved the Constitution, I wouldn't care what she looked like. Mrs. Carson is pretty much tied with Mrs. Obama in looks, except that she knows how to smile, and her husband loves our country. Those two factors matter a whole lot more than wearing expensive dresses.
I don't understand what Michelle 0bama's looks have to do with anything, and especially why her looks would be an issue depending on whether her husband is a good President or not.
Personally, I believe that constantly degrading someone based on their "looks", especially a First Lady, is rather mean-spirited.
Mrs. Carson probably loves her country, too. That matters a whole lot more than how she dresses. The kids who eat school lunches would probably rather have anybody running the show than the commie Mooch.
