that actually has a reasonable chance of getting in
unless you’re willing to vote third party
To be abundantly clear, with the system as designed in the US, third party (presidential) candidates do not have any chance of “getting in” this election, let alone a “reasonable” chance (in certain areas, some options may exist for lesser political appointments).
Voting third party is at best a weak attempt to signal preference for future elections, but at worst a gift to whichever party or candidate you consider to be “most bad”.
By all means, protest vote in the primaries, campaign for candidates you believe in, and most importantly, discuss the issues that are important to you to help bolster public awareness, but please, PLEASE, don’t fall for the con that is voting 3rd party in the election.
I don’t know who your third party favorite is, but do yourself a favor and look at who is donating to their campaign, and what other campaigns those donors support - a lot of money is thrown at 3rd party candidates to draw votes away from credible political opponents.
