This is about as impractical thinking as idealism can get, and I’m an idealist.
Always, always vote for the lessor of two evils when the others have no chance. Violating this axiom gave us first Bush II and endless war and hundreds of thousands of deaths. Then it gave us crime boss Trump and the possible end of our democracy or even an all out nuclear war if that’s what the Donald thinks it will take to preserve his power.
When your life and freedom are on the line all other considerations are of little or no consequence.
