Just a thought, here. I've never watched those "reality" programs, where people call or text to vote on their choices, but haven't there been some spectacular fails from some of those? Cases where an obviously better performer was tossed because the public voted for the flashier, but less talented, contender?
The other thing to consider is time. How many people would really want to spend the time studying all of the nuances of a particular issue before voting on it? How many would even bother?
