Frankly, anger management classes might not be a bad idea for many politicians. But this is the first time I'm aware of one actually being ordered into anger management classes.
Washington State Senator Pam Roach was banned from caucus by the Republican Party (you know its bad when your own party suspends you!) with a very strong "suggestion" that she seek anger management classes. This is the second time she was suspended (the first time was in 2003) for verbal assaults on her staff. She has been reprimanded five times for her anger management problems over the last several years.
Roach denies the allegations, stating that "This is a leadership that wants to persecute me". That might set off some bells for you if you've read my free white paper report on "Denial and Anger Management"
