Decent authority it is bad for Obama but can easily be spun against Romney for releasing it (which may indicate a third party, independent release).
How many people (besides me) are tired of this meme? The MSM is trying to make Republicans gun-shy and self-doubting about challenging Obama with his own facts on the grounds that ANY challenge to Obama will hurt the challenger more than Obama.
We can't let them scare us into inaction by floating worst-case supposeds.
JUST DO IT! and let the chips fall where they may.
