Trump is in no way representative of the country as a whole. He exists as a phenomenon because a relatively small minority really likes him, and because the Republicans have not managed to find any candidate even slightly worthwhile.
When you see that Trump is polling at 31% or whatever, keep in mind that 31% of early Republican primary voters is a pretty small number of people. With a more normal candidate you might take that as being in some way representative of the wider population, but Trump is probably not going to gain much more support than he already has, since he's so extremely polarizing.
