How can you hope to change your result if you don't change your systems?
Other than campaign financing, the system is in place for more than two serious candidates. Put a cap on spending for each political office and then perhaps an independent would stand a chance.
The nonprofit Center for Responsive Politics estimates spending on the Clinton-Trump contest at more than $2.65 billion, actually down a bit from $2.76 billion in 2012 when Democratic incumbent Barack Obama defeated Republican challenger Mitt Romney.
Unless you are a part of the current two party plutocracy, you don't stand a chance. Capping the presidential campaign spending at say $100 million, may allow other voices to be heard and serious campaigns by other independent candidates. But, don't expect the 2 party plutocracy to allow that to happen. Current politics is just like any other large business; they enjoy the monopoly they have.
