Any question why Bernie is most popular politician in the WORLD? Not just America.
The whole world is watching. Behave accordingly
The rest of them pretend to be progressive, claim to present progressive policies, but Bernie is the ONLY one who has the history, the consistency, the record, and the authenticity to make this claim. He's a role model of what the Left should do and hasn't done (in any country) for decades: stake your policies and principles, stand by them, even when the mainstream laughs, keep standing until they stop laughing, and believe in what you stand for, and change the debate and the prevailing orthodoxy.
