I'm going to address Stein first. A single payer health care system is the only justifiable health care system IF we want to consider health care a fundamental right. Is it?? In my opinion, yeah. What made Sanders so attractive to me was that he was unwilling to give the insurance industry access and therefore control of the health care system, in short, making the entire greedy, cut throat paper pushing industry into a buggy whip. What Obama did was outrageous, forcing free Americans to honor a greedy industry's terms, hence trying to force Americans to submit to oligarchic control, but I digress.
To your - I think - second point, both Democrats and Republicans pander to big money. I've never denied it. But there is a big difference between being surreptitious about it and being blatant about it. The Democratic elitists try to deny their corporate interests, their monetary aspirations, or their nefarious interest in quashing freedom, but it's right there evidenced in their legislative efforts. And they mislead the public about their true intent. The Democratic elites were the ones that attempted to discount Snowden's startling revelations about government intrusion. But it was the likes of Paul and mostly Republican effort that pushed for reform. As I recall, certain Democrats only got on board when they found out that they themselves were victims of our government security agencies, of which we have too many, but again, I digress.
As far as Trump lying, I actually think people give him too much credit. Everybody lies, I suppose, but most of our two party politicians make a habit of it. I think for them it's a question of political survival, and the power they have must be addictive. So, they take credit for things they shouldn't; they misrepresent their motives; they stonewall claiming it's to benefit Americans - ie Pelosi's gang right now - when it's really about securing their own jobs and defeating any challenges to their hold on the country. With Trump, I just don't think he's as calculated as his detractors would like to believe, and lying for nefarious reasons takes both calculation and consistency, of which he has neither. Thanks!!
