His principles? You mean socialism. The principles literally responsible for hundreds of millions of people being murdered by all powerful government?
That's a good thing?
it seems like you're being too simplistic, which is likely not your intention.
Sanders is far closer to the Scandinavian Social democracies than say Stalin's Russia. [In fact, the body count inflicted by the USA on civilians in places like Vietnam & Iraq make Bush/Clinton better targets for your talking point]
Sanders is much closer philosophically to John Dewey than he is to Vladimir Lenin. Dewey believed in regulated markets and private property, but, politically, he wanted to replace the concentrated power of wealth with broad civic participation.
Sanders has proposed a lower marginal tax rate than Eisenhower, Nixon or Ford.
I've given up on Sanders because I think he is this cycles' Nader, but your inability to make very basic intellectual distinctions between different political and economic systems is catnip for our political leaders, who prey upon those who don't have time to go to a library.
Rather than letting Bush/Clinton sell you on the notion that Hussein and Bin Laden were part of this oversimplified monolithic cauldron of evil, you would do well to study the regional complexities of the Middle East. We need people like you to understand the convoluted tribal conflicts between say Shiites and Sunnis so that you can understand the challenges of nation building in Iraq and Syria. To merely throw your hands up and label everyone a socialist or Islamo-fascist is to leave all the heavy lifting to others. When Trump says he's just going to go over there and kill the "evil doers" - who are strategically embedded with the moderates we need to influence - it is your job to wipe the slobber off your lips and be analytical.
(And I'm not saying you have to give up your hatred of gays, Islamists, Mexicans, socialists, communists, atheists, multiculturalists or the Western European welfare states; rather, I'm trying to help you land better punches)
