The openly racial campaigning and bringing up the past is scaring some Indians, but turning off the few Afros who vote PPP. Also turning off some of the relatively larger mixed population who vote for PPP. The election has teeth. For the first time since 1992, I can't say PPP will win an election. None of this is helpful when the Indo population is between 35 to 39%.
The interior has 11% of the population, yet only delivered 6% of the votes in 2011, not all from Amerindians. The virtual non participation of Amerindians in the electoral process also increases the importance of the Indian vote above its numbers, in addition to the fact that many mixed voters are either too young top vote, or are in that "irresponsible" phase that we go through between 18-25 where many don't take life seriously, so don't vote.
