Quite, but the point still stands. Democracy gives 100% of power to the person who can convince 51% of the public. In reality in the US sometimes you just need to move the needle by a few thousand votes to make a difference, certainly changing 5% of the public views (either to flip or to stay at home or not stay at home) will settle it in your favour.

We have a trillion dollar industry designed to manipulate peoples views. Nobody is smarter than that.
