When the RAT party accuses Republicans of fraud, they are doing one of two things: trying to shift the issue away from their own fraudulent activity, or (perhaps and) bragging about the fact that they got away with fraud and they know their accusation against Republicans will carry more weight than vice versa.
You have to understand a liberal: right and wrong are totally dependant upon whether you support liberal theology or not. If you do, you are right, lawful, and telling the truth. If not, you are wrong, illegal, and lying. It's no more complex than that.
