You are listening to all of these attack questions and think he is doing a bad job? I think he is doing great, because he is remaining calm and is explaining things to the people.
People listen and see things like this through their own filters. Thus we all see it somewhat differently based upon what it is we expect to see, hear or want to be communicated.
Look at this thread...... Some see the President doing great, wiping up the floor with the Press people. Others see it the opposite as he's a complete failure, can't communicate, won't support his base, afraid of hurting someones feelings,etc..... Then there are the one issue types who will not have a kind word to say but threating for the umpteenth time to leave the party and never vote Republican again.
Most likely the truth is that the event falls somewhere in the middle of these extremes. My guess is only political die hards follow this stuff and even watch it. So in the long run not a lot of people will be swayed one way or the other... Just my two cents...
