Pls help me find a site where I can view and vote for the presidential candidates.

Only a poll conducted on a platform like facebook over a very long time (say 1 month) can give a fair idea of what the perception is like. Many polls around have serious flaws. Multiple registration, Manipulation of figures, etc. If the starter is a PDP supporter, he will register several accounts and vote for PDP. If the starter is a BB follower, same same. I haven't seen any one properly done yet. If you find anyone done on facebook, it will make more sense because there are more controls and there are more people to sample opinions from.
