How about we finally start working towards a 3rd party?
What do you mean "finally"? People have been trying that over and over and failing for over 100 years. It would be great to have a multiparty system, but there are unintended structural forces in place that will always prevent that. None of us alive today created this system. We are all stuck with it just like you. But ignoring reality just makes someone into a lifetime loser. There is nothing you can gain by making yourself into a lifetime loser.
