He hasn't.
There hasn't even been a vote yet. Obama has only made a statement that he supports passing the current legislation. He's doing what he is supposed to be doing. Voting with his conscience. He has listened to his constituency. He has considered the evidence that we are not privy to. He has explained his position. He's even said it's not a Bill that he would author. But it's enough of a compromise.
Does this mean we have to agree with him? No. Does this mean it's ok to feel that he's wrong? Yes.
But has Obama failed us? If you believe that, then you have not considered what it is like to be Obama. You have not put yourself in his position. And you are not giving your leader the benefit of the doubt.
Obama has proven he has what it takes to be a great leader. If he were President, I guarantee the current FISA bill would not be an issue. And that's what this is all really about.
As another poster has said here:
"Keep on keeping on. Keep working to get in as many REAL progressives in Senate and Congressional seats as humanly possible. Keep educating the public. Keep protesting. Keep speaking out."
But don't jump to the conclusion that our leaders are failing us. They need more help than they are getting from us. That much is clear.
