I don’t see much of a slur here; every you look at Obama, and Edwards as well, you can picture them as spoiled snotty brats in short pants and beanies running around carrying all-day suckers and constantly whining about something or other.
Rational people wouldn't see it as a slur. However, if this sentence had come out of the mouth of a Republican, much like "Plugs" Biden's "clean" remark about Osama Obama, it would be front page news (above the fold)......for weeks.....
