It’s good to be someone who thinks about politics, and I like your thinking. A true liberal should never feel able to support Bernie Sanders because although he’s a likable man and shows signs of still having some principles, he’s a socialist.
And as the Austrian economist Josef Schumpeter said, and as we have seen demonstrated many times around the world, “Socialism always leads to fascism.” (He also said capitalism contains the seeds of its own destruction.)
Hillary Clinton is not a liberal, she and her hubby are corporatists, corporate business and the corporate state, the partnership named by Benito Mussolini in what is the only meaningful definition of fascism as a political philosophy.
My view of the world is that the political units (nation states) have become too big. In a nation of 300 million, a nation of 60 million or even a nation of ten million government is to remote from the individual for there to be a meaningful relationship. The only way to solve the problems of the democratic world that I can see working is to decentralise, give power back to communities, and for social and financial policies to favour small business rather than favouring ever larger and more unaccountable global corporations.
For the record I have never voted for either of the main UK parties, Labour or Conservative. I was once active in the Liberal party, later I voted for the hybrid Liberal Democrats and retained the hope that if they ever came near power they might offer something different and more human. but when they came close to power they sold out immediately to the corporatists.
Since then I have cast a protest vote for whoever was on the ballot, Green, UKIP, a local nutter (The Idle Toad party) and The Pirate Party, but only the Pirate Party have deserved my vote — because as a child I loved Long John Silver :-)
