I'll always maintain that the worst liar is the one who thinks they don't. Unless your ethic is God-clean (or wholly impractical vis a vis Kantian ethics), lying is a human part of who we are. Furthermore, to accuse one person--even better, a politician!--of lying when they all do it (and oh-so-regularly) implies that you're grabbing at straws that have already been plucked from the ground of fertile right-wing soil.
Think for yourself for a minute...or two. And then accumulate a few of those minutes and gain some empathy. Realize that we all suffer from what some have coined as the Human Condition. I'd sooner have an intellectually-superior, emotionally-restrained, egalitarian in office than an excitable idealist.
It's no wonder that the Hillary camp is so empty. Perhaps one must be like-mindedly competent to vote for the same breed of intelligence.
When Obama can finally give his own opinion on when life begins, or whether or not "ethical treatment" applies to all humans, perhaps I'd consider his own ideas worthy of debate. As of now, his ideas are all only mere possibilities. It's a sign of his lacking ability to make decisive choices on his own that makes this primary campaign so unbearable at this stage of the game.
From a logical point of view, just about everything is possible. Making it happen is something entirely different.
