This is not an insurmountable problem, you're just solving it in the wrong place. If you want a "third party" candidate to win then what you need is for that candidate to win a major party's primary. What is necessary is for people to stop voting for parties whatsoever and vote for candidates instead.
"if a candidate from e.g. the Green party could actually win an election, the Democrats would just run that candidate on their ticket"
If the Democrats are drifting too far to the right (i.e. the situation we have right now), then liberals need to vote third party -- until the Democrats get their act together.
We will keep having corrupt government as long as we keep voting it in.
When the system becomes corrupted, corruption is really hard to beat from within the system.
There are so many hurdles, well beyond apathy. If there were real meaningful action anyone could take, they would also face the threat of a government that attacks those who criticize it. If that weren't an issue, you would still have to contend not with the apathetic, but with those who enthusiastically accept and promote what is being done in some bizarre sense of self-preservation from a big scary world, because they're deathly afraid that some evil underwear bomber is going to blow them up next time they're on vacation to grandma's house.
There was an episode of Boondocks that did this. In the end, Ann Coulter turns out not to be a republican. She's just faking everything to cause controversy sell books.

We have no one to blame for the current state of affairs but ourselves. To attempt to pin the blame on anything else is to fail to accept that responsibility, which is tantamount to failing to recognizing the problem. And of course, if we fail to recognize the problem, nothing will ever change.
Which is quite impossible to build if you have to struggle for your daily bread or pay your mortgage. Even when you're idle, you're most likely arguing against or for abortion and other bikeshedding issue instead of focusing on important issues.
We can talk about reproductive rights once we have restored basic civil rights and reined in the executive branch of government.

Hitler himself wrote in an early edition of “his” book – a book that is written in the most awful German I have ever read, despite which the nation of poets and thinkers have elevated it to the status of the Bible: “You would not believe how one must deceive a nation in order to rule it.” If this cancerous growth in the German nation was not too noticeable in the early phases, then that is because there were enough forces for good at work to try to slow its growth. But as it grew larger and larger and finally ascended to power by means of one last vulgar corruption, the abscess erupted and defiled the whole body.
This caused the majority of its previous opponents to hide themselves. German intelligentsia took refuge in holes in the cellar like Solanaceae, hiding from light and the sun, gradually suffocating. And now we are facing the end. Now it is a question of mutually coming to our senses, of mutually keeping one another informed. We must always keep these things in mind and allow ourselves no rest until the last man is convinced of the utmost necessity of his battle against this system. If a wave of insurrection surges through the country, if “it is in the air,” if many join us, then this system can be cast aside with one last mighty effort. An end with terror is always better than terror without end.

But our present State is a dictatorship of Evil. “We’ve known that for a long time,” I can hear you say, “and it is not necessary for you to remind us of it once again.” So I ask you: If you are aware of this, why do you not stir yourselves? Why do you permit this autocrat to rob you of one sphere of your rights after another, little by little, both overtly and in secret? One day there will be nothing left, nothing at all, except for a mechanized national engine that has been commandeered by criminals and drunks. Has your spirit been so devastated by rape that you forget that it is not only your right, but your moral duty to put an end to this system? If a person cannot even summon the strength to demand his rights, then there is nothing left for him but destruction. We will have deserved to be scattered to all corners of the globe, as dust before the wind, if we do not pull ourselves together in this eleventh hour and finally summon the courage that we have been lacking till now. Do not hide your cowardice under the cloak of cleverness! Because every day that you delay, every day that you do not resist this spawn of hell, your guilt is steadily increasing, like a parabolic curve.
Many, perhaps most of the readers of these leaflets are not certain how they can practice resistance. They do not see the possibility of so doing. We will attempt to show you that every person is in a position to contribute something to the overthrow of this system. It is impossible to lay the groundwork for the overthrow of this “government,” much less to effect its overthrow as soon as possible, if one opposes it alone in the manner of embittered loners. This can only be accomplished through the cooperative efforts of many unshakable, energetic people – people who are unified regarding the means necessary to achieve their goal. There are not a great many choices we have regarding the means to use; one and only one is at our disposal – passive resistance.

Clearly, it is impossible for us to give every individual specific guidelines for his personal conduct. We can only allude to general issues. Everyone must find his own way to realize resistance.
Sabotage in armaments factories and other businesses vital to the war effort. Sabotage in all assemblies, rallies, festivities, organizations that were breathed into life by the National Socialist Party, prevention of the smooth operation of the war machine (a machine that operates only for one war, one that focuses on the preservation and maintenance of the National Socialist Party and its dictatorship). Sabotage in all scholarly and intellectual realms that exist for the continuance of the current war – this whether it be in universities, colleges, laboratories, research facilities, or technical offices. Sabotage at all cultural events that could possibly exalt the “prestige” of fascists among the people. Sabotage in all branches of the fine arts that have the least connection to National Socialism and serve its goals. Sabotage in all areas of literature, all newspapers that are on the payroll of the “government”, and that fight for their ideas, for the dissemination of the brown lie.
