DovBear unwittingly "reverse fisks" us by proving our point. His numbers demonstrating the low level of support among Democratic voters for Sharpton only emphasize the absurdity of, for instance, Sharpton's speaking at the Democratic convention.
It may be possible to distinguish here between rank-and-file Democrats opinion of Sharpton and the Democratic leadership's view, but there is no denying that the leadership gives Sharpton way too much face time. And, as DovBear helpfully points out, it can't be because of his popularity with black voters.
