Unfortunately, a number of ordinarily honorable individuals have been browbeaten, blackmailed and coerced by higher-ups in the Dem party into doing and saying things they would not ordinarily.
This of course does not excuse the Governor. If the story is true, I wish she had the spine to tell Dean and his accomplices to go jump in the lake (or something stronger).

As it turns out, she shows herself to place her party above the citizens of her state.
