Lefty, right, and sentry
First, what is "lefty leaning", as you describe Mr. O'Brien? Somebody not ideologically committed to be left-leaning, yet with a soft spot in his heart for tunes such The Red Flag and the Internationale?
Second, you describe Georgia as rejecting help with its voting systems as "a power grab from the centre". By "centre" do you mean the federal government? It is never so called in the US, and for that matter only real-estate developers ever spell the word "centre".
Finally, faith in democracy is my experience pretty rare. At any given time, a large chunk of the US would like to disfranchise another large chunk of the US, mostly on grounds that come down to "not voting my way". The jurist Learned Hand once said that in his worst nightmares he was the defendant in a trial by jury; what he thought of being governed by system that requires not unanimity nor even a majority, I haven't read.
