In another thread a story was mentioned in which
a small part of which is where the protagonist steps in to get specific people elected to forestall problems.
His argument is that every elector has about ten areas in which he/she is strongly interested - perhaps religion, perhaps race ... but candidates only express opinions on perhaps two of those. In consequence for an individual voter his choice is for a candidate who fits two ideals but the voter doesn't know that his other eight interests are against the candidates' views because he never answers questions about them.
I've made this thread to continue that query without cluttering the original thread with too much off-topic stuff.
