I'm going to avoid the current system/proportional system debate and say what I think could get more third-party candidates elected: wealthy benefactors. Third-party candidates' problem is that they usually can't afford to make their names widespread. Since they're small-time, the news networks don't cover them, and they don't get invited to major debates. This further marginalizes them, perpetuating a vicious cycle.
If they had backers with big wads of cash, they could buy more advertisements to get their names and platforms out, and thus gain too much attention to be ignored. Of course, this money could also come from average joes, but the reason we're having this conversation is because not many people support them!
