"Brim's attorney James Montgomery said Wednesday that his client has bipolar disorder, a condition she has controlled with medication, but that at the time of the attack she was "legally insane," the Tribune reports. The Chicago Bar Association previously recommended that voters reject her from the bench and ten of 11 bar associations have given her negative ratings, though the Democratic Party has continued to back her."

The Democrat Party would have continued to back her if she whipped out a machine gun and mowed down everybody in the courtroom. And the Democrats would have still re-elected her.
That's just the way it is.
