The numbers on that report indicate that blacks are extremely tribal.
Why not. When people like you scream that blacks are a scourge,they are cursed and they are the worst people on the planet, it is in the interest of survival for them not to vote PPP.
Telling a black man to vote for the PPP is like telling a Jew to vote for Hitler. The PPP harbors racists like you and does NOTHING. In fact Rohee's daughter said much the same about blacks as you did and her5 father didn't see anything racist about that.
Note that mixed Guyanese also reject the PPP by number almost as high as do blacks. Africans +mixed are now 50% of the population!
