Why are Bill C.'s attacks on Obama given so much play while Michelle Obama's attacks on Clinton are given none?

And how much sleazier can you get than strewing the path of your entire South Carolina campaign with vocal, openly gay-hating preachers and entertainers?

You're right--sleaze (and money) are the orders of the day. But when the Clintons do it, it's news. When the Obamas do it, it's completely ignored.
