Don't know if you could call the war a "betrayal," though some of the mismanagement could fall into that category.
There's also Katrina, not exactly a betrayal, but one of the straws that broke the camel's back.
If it were just the spending and deficits, voters would complain but put up with it.
Katrina? Unless your complaint is that we spent too much money on Katrina, than I don't know what you mean.
