This is obviously absurd. If choosing from the legal options in an election is being part of a "conspiracy" then the whole system is already failed and you yourself are a conspirator for not doing anything about it.

And no, voting one of the same two parties that have brought all this mess in the first place is not doing something. The Reps and Dems are equally responsible for the desolate state of the US democracy. So by your definition of "conspirator" you have conspirated to bring about the conditions in which Trump not only was elected, but has a chance to be reelected.
