I am in agreement with your assessment but believe you have let one neglected prejudice cloud your thoughts.

There is no left or right in politics any longer, never is when lobbying is possible. The powerful control ALL the parties and all the media that shepherds the bulk of the electorate. Very few are immune to the fear thy neighbour propaganda and even fewer political candidates are able and prepared to resist the greed, bribery and blackmail of the well run system of coercion to remain honest.

We need to vote for those that are the most likely to dilute the political control that is nearly complete.
