This is all about demonizing the Brown supporters which is a classic Alinsky/leftist tactic.
It is also because John Kerry has to face the ire of the 58 other remaining Senate RATS:
1. Kerry failed to deliver Martha — and failed to recognize over the holidays that Scott Brown was quietly building momentum
2. More significantly, it was Kerry who engineered the State Legislature to change the law in 2004 such that the Governor would not appoint an interim senator that would serve out the remainder of the term until the next election. Kerry was so brazenly confident that he’d win the presidency that the RATS passed a law, over Governor Romney’s veto, mandating a new election so that Mitt Romney would not be able to appoint a Republican to the seat. Had they left the law alone, Governor Patrick would have had a RAT in that seat until November 2010.
Sweet irony and just desserts for these people.
