The bad: no, it isn't Bernie's rumpled appearance (that he can get away with because he's - gasp! - a male) that is putting him over Hillary. One's a septuagenarian crazy uncle who's promising them free money. The other is a nearly-septuagenarian totalitarian criminal who wants to control them. Guess who wins that one?
Socialism and its etymological offshoot "social justice" are systems consisting of theft and justification for theft. Political power confers the ability to commit theft without consequences - need I say more than "Hillary Clinton" to make that point? And so, with moral justification, however weak, and no consequences, we have the enshrinement of theft, a kleptocracy, a socialist paradise until the other people's money runs out. That, unfortunately, tends to be swift and irreversible. But that's for tomorrow, and tomorrow never comes.
Bernie is the loss-leader. Hillary is the reality.
