Being a liar and a fraud is what being a politician is all about.
So true. In politics (almost all of the time) you have to work all the way up from a local level to get to the top.
As being successful in politics is all about compromising and making backroom deals to get the support required, any of those with high ideals, or who have any sort of desire to put the needs of the many above the needs of the few, get weeded out with a quickness. Only the deeply slimy bullshitters get to the top.
That isn't an indictment of American politics, it's true the world over.
