As Prof. Murray noted, while McCain swept DC's GOP presidential primary, Huckabee fought him to a draw among the few voters who turned out in heavily Afro-Am precincts. East of the Anacostia River, Huckabee bested McCain by one vote 58-57 in Ward 7 and lost Ward 8 by a 35-36 - votes, not percentage points, mind you (this, despite "Former Mayor for Life" and incumbent Ward 8 DC Council Member Marion Barry's tongue in cheek endorsement on MSNBC's "Tucker.")
More evidence of strong Huckabee performance among black Republican primary voters can be found on a map of the Republican primary in Milwaukee city. Prof. Murray breaks down Milwaukee ward demographics at this post.
This trend is further confirmed in heavily black precincts in majority African-American Prince George's County, Maryland, where Huckabee captured District Heights and Bladensburg and nearly tied McCain in Oxon Hill. Also of note: Alan Keyes, a two time GOP Senate nominee in the Free State, waging a half-hearted campaign this cycle, made it a three way race in Seat Pleasant and Capitol Heights.
