Ok, let's try again. Those who like the left usually don't vote for the GOP, agree?

Yes.

Then, for them, the options are three, either vote Dems, vote third party or don't vote. Now, if, like in the example of before, these people are that 5%, do you agree that not voting or voting a third party will result in the GOP winning, while voting for the Dems will result in the Dems winning?

Sure.

If you think that the Dems and the GOP are one and the same, then fine. If instead you'd rather the Dems win, then do you agree that these people should vote Dems rather than do nothing or vote for a third party, which would lead to a GOP win?

Is there a material difference that results from what I personally feel? Shouldn't your question be "how can we get the 5% to vote for the DNC?" The Dems are right-wingers and enablers of fascism, if they took strong stances against it and pandering towards Leftists then they would see more Leftist support. The fault lies with the Dems for not analyzing their own positions properly, if they want Leftist support.

Btw, this is why there's no third party in a fptp system and there can never be one. Your votes are better spent on the candidate you dislike less rather than on the one you actually like, because voting for the one you like will inevitably result in the one you really dislike going to power.

I understand that the US is not a democracy, that's why more than voting, it's important to organize and build up dual power.
