The voting system is not the problem. The logistics of running a successful campaign are. The amount of advertising, canvassing, fundraising, and other effort that goes into American politics is insane - and unless you have the backing of a party, you are quite literally fighting an uphill battle.

Recall the republican voter list leaks last year. Now, consider how much money it would take to gather that much information, at that level of fidelity. Now, consider how much of an advantage a sanctioned party candidate has, when you run against them.
