I don't think you should limit what you read.
Accountability doesn't mean apologizing.
A lot of news is just entertainment masquerading as news.
If the state polls are right, then Mr. Obama will win the Electoral College. If you can't acknowledge that after a day when Mr. Obama leads 19 out of 20 swing-state polls, then you should abandon the pretense that your goal is to inform rather than entertain the public.
I'm not trying to do anything too tricky.
If you have reason to think that yesterday's forecast went wrong, there is no glory in sticking to it.
