Very specifically, in the upcoming US election. Going to say, yes you need to stop a certain tyrant from getting another term. But as a general comment this happens regardless.

Even all the years, at least in the UK, for quite some time a decade or so ago we had two parties, one that was 1mm left of centre and the other 1mm right of centre. If people didn't like the fact they had a choice of Kang or Kodos, they did. But, everyone voted that way anyway.
