It's a matter of fundamental core values applied to situational matters. Opinions and preferences shift as time goes by. The populace sees this in the politicians of today. Bernie's actions are lauded not because they are the same, but because they represent an integrity to the core values of human life & equality. Politicians claim to value life & equality, but manifest their hypocrisy by going to war and endangering soldier's lives for profit. This is the disingenuity of the status-quo politicians.
