The problem is if you play their games like they play them you legitimize everything. If you start cheating like they do, their lies about you become truth and it's all down hill from there.
The only chance the country can be saved is if the electorate wakes up. Part of the country still playing by the rules allows us to be able to go back to all of the government playing by the rules. If they give up on that, there is no coming back.
It starts at the local level. National 3rd party candidates are just spoilers used to split the vote enough for one side to win when they wouldn't in a 1v1. Until the third party builds enough momentum in city->county->state elections they will never be viable nationwide.
Instead of focusing on the national, they need to pick a few places to focus on and grow viable candidates throughout the whole process. If they can flip one state to the third party, then we might start talking about their viability.
