This has degenerated into nonsense.
We have people who claim they can't afford the docs of their choice (informed choices; how are they to know what's what - are they medics too?) supporting a system that puts them where they are; we have people who can't afford the system and are ready to walk away from it still supporting it. If that's not blind political allegiance over common, personal experience, than pray tell me what is or can ever be.
Political choices can be very irrational ones, often based on the assumption that the person holding the allegiances actually belongs to the group that benefits from them when, in truth, that's an ideologically wish-projected choice and not one that's practical or even vaguely applicable, representative of, or helpful to them in their actual station in life. It is turkeys voting for Christmas.
Were these same people within the top 5% of earners, then yes, they'd have a logical reason for their political choice; for their personal realities, gobble gobble gobble...
But I'm not blaming the American population alone: we have our own half-nation that's as blind and politically manipulated as you do over on your shores. They believe politicians who have great personal wealth, are in positions of power where they can protect that wealth if they can manipulate the laws to their purposes, actually to be working hard to represent them, the proles, and their proletarian better-interests. How friggin' naïve can one be?
It took until last century for many of us to get a basic set of human rights of political representation, and now we have become slothful in our attention to the machinations of politicians to the extent that we think it safe to stop worrying and just vote on the basis of handed-down family loyalties. Europe seems, in some cases, to have woken up to that fact, which accounts to some degree for the emergence of many different power centres rather than as blind loyalty to the previously rigid split into two, left and right. Get ready America, your people will wake up too.
