This is the whole point. Once you achieve a powerbase such as the caribbean, its hard to be deposed. Thats why Jack is world footballs most powerfull man. He's the power behind the throne. Its said he controls around 50 votes.
There is a similar powerbase in Africa, but Blatter owns the third power base and this, coupled with Jacks, ensured Blatter won the last presidency.
remember the story about a staff member pretending to be the Haiti delegate and voting in an election?
But this power and control makes Jack unpopular with many countries. He's achieved many good things for T&T, but also taints peoples perception of Trinidad & Tobago. T&T made many friends on the football field while Jacks making enemies in FIFA.
