I don't know what her record was like before 2009 but, aside from the stimulus vote, most of her votes went to support the cause of creating obstructionism and dysfunction in the US Senate and her "moderation" and "independence" have largely been a joke, particularly when it came to her hemming and hawing over health care reform, which she was willing to vote out of committee but unwilling to vote for in the end (despite essentially being the same bill) out of deference to the teabaggers. Her laments about the state of hyper-partisanship and gridlock (confined almost exclusively to the Republican side of the aisle) seem particularly stupid and/or hypocritical given that she supported the near-permanent state of filibuster that the Republicans have put on the Senate since 2009. Good riddance.
*ugh*
