Let's start with the Fox News Channel crawl above, which refers to the wife of the Democratic presidential candidate as "Obama's baby mama," a phrase which, the Journal helpfully points out, refers to "the mother of a man's child, who is not his wife nor (in most cases) his current or exclusive partner." Expect to see a lot more of this throughout the campaign, which is actually a good thing: It's really going to raise the bar for the folks at Fox, who are going to need to come up with creative new methods of coded racism when they disparage the nominee and his family.
