madamab at Oooh, nuance! discusses why so many of us cannot trust Barack Obama. Short version: No record and a habit of lying about pretty much everything. (Seriously, read the entire post) Two snippets:
It would be "the height of ideology" to stick to a campaign promise that you used to win the anti-war left to your side? Seems to me that it is the height of cynicism to pretend you are something you're not.
If Senator Obama will pull back from his campaign position on Iraq, what else will he "change" his mind about?
How about FISA?
So no, please don't tell me that he and Hillary Clinton believe in the same things and would fight the same fights as President. The fact is, I don't have any idea what Barack Obama believes in. I have no sense of what his goals are. He would have to actually do something - pass a law, take a stand, make something happen in the Senate - in order to push aside that fog of cynicism even the eensiest little bit.
