Why do libs ignore their representatives' actions and behavior?

One can have a belief system, but why condone behavior that is not legitimate? Rangle-----got away with TAX EVASION and no one on the left seems to care. John Kerry-----docks his yacht in Del. to avoid HIS OWN STATE'S taxes. Biden reports job growth in zip codes THAT DONT EXIST. Obama promised bills would be on the internet before voting on them-------flat out lie. Why do libs allow such disregard of truth and honestly from their public representatives?
