Word for the day:
Pretendisentative:
someone elected to represent you, but pays no attention to their constituency, infers they are liars until proven innocent, works generally towards the worsening of their lot in life, does whatever they want despite strong opposition from their electorate, and tells their voters how stupid and un-knowledgeable they are.

not sure if this applies to any particular person... but I can definitely see using the word.
