Each system has potential weak points. The one thing I envy about the UK system is having to possibility for a "vote of confidence" in the middle of a term.
   The greatest flaw in the US system in the electoral college. The Republicans are totally aware that changing demographics mean they MUST retain the electoral college in order to keep electing Reagans and Bushes and Trumps.... it is possible that they will also need ongoing tampering with elections.

   Over 40 million young people have turned 18 since 2016, and we shall see how many are taken in by the current batch of lies.
