I think it is important to note that one would have to know (be familiar with) each candidate before one could make that "snap-judgment" of a choice. It sounds as though many people are still learning about the possible choices. I have studied every candidate enough to make an informed "snap-judgment" decision, and all the new information is just more confusing, but entertaining.
Not to be a smart-aleck, but isn't this contradictory? Familiar as in "I saw that dude on the news last week while I was vacuuming", or as in reading their websites, or as in reading what their opponents have to say...?
