Presidential elections and 3rd party candidates are not viable until the system is changed so losing candidates can transfer their votes or a percentage of them if they have passed a bar of a percent or a few to weed out spurious candidate proliferation. You don't want Italy style ballots.
The only other way is to elbow in a third party with real numbers in the houses but during that... Third party as a protest in presidential seems tears in rain to me and probably hurts you.
West is clearly a good man, he is not even a Bernie in ability to inspire enough.
