And of course there's Hillary...

a/k/a What's Wrong with Hillary:

[W]hen you look at the positions she has taken on some of the most significant public policy questions of her time, you cannot escape noticing one key pattern: She has always embraced the politically popular stand—indeed, she has gone out of her way to reinforce that stand—and she has shifted her ground in a way that perfectly correlates with the shifts in public opinion....Is this kind of analysis subjecting Clinton to a double-standard? Don’t politicians of all stripes change, “evolve,” calculate? Almost all of them do. (Although in the case of Bernie Sanders, you get the sense that if he were told “the building’s on fire!” he’d explain that was because of inadequate regulation caused by the power of millionaires and billionaires to rig a corrupt system that requires a revolution. Not since Cato the Elder ended every speech on every subject by declaring “Carthage must be destroyed” have we seen such consistency in a politician).
