Post Citizens United, Why be Surprised?

Earlier today, I read that federal judge in VA declared unconstitutional the ban on corporations donating directly to candidates, and that the judge cited the infamous Citizens United case in his reasoning.  I, like many, many people, felt that the Citizens United decision was a travesty, and that it represented Pandora's Box with regard to American elections.  The only seemingly redeemable aspect of that case was that it upheld the very ban that a judge has now declared unconstitutional.  I cannot see how this conclusion is not upheld by the SCOTUS, should the case come to it.
