Both of these are links to rap videos where candidates for mayor in Birmingham and Atlanta are depicted in "rap" videos. 

Now anybody with half a brain knows that if you use patronize black folks they will turn on you faster than a rabid dog.  So are this videos depictions of political humor or just plain sabotage by surrogates for the opposition of these candidates? 

It seems to me that they just might be considering how contentious both of these races are and considering the key demographics of the swing voters of both cities.
