Everyone here missing the point that America never has been a democracy and your choice has always been an illusion. The rest of the world knows this from the USA invading every other country for freedom and democracy. Who wins doesn't matter. The poor, the global south, minorities, women, etc. will all get screwed over unless you literally fight back.
This seems like pretty strong evidence for always voting against the republican party, especially considering the later actions of Carter concerning this situation.
In essence what you've shown is proof that the Republican party is always worse for the world as a whole than the Democratic party. Good job!
