Right or wrong, it is fair to assume many will cast their vote without doing the reading in such a system. Speaking from a German perspective, I sometimes think how inefficient it is to count 60M votes - just counting 1M votes will give you the exact same result, iff you get the sampling right. What if we could choose a subset of 1% of citizens at random for every election (still far too many to directly bribe), giving them some pride in their responsibility, make sure they have some/better access to the candidates etc.. Again, if the sampling is sound, this won't change the outcome (other than the average voter being more motivated/informed). Of course, I see the problem that people will not feel represented if they, by chance, never get to vote in their whole life ...
