Democrats are afraid of Swiftboating- the act of revealing the truth about a democrat at a crucial point in the election. General elections become more free-wheeling and less in the control of the conglomerates who own the mainstream media as a result of the decision.
And on a related subject- did you notice that John Kerry refused to stand while applauding Obama’s attack on the majority in Citizens United v. FEC? Interesting. A Scott Brown effect?
