Voters for the most part seem to miss point like you bring up. I doubt the job pays much more than say $150,00.00 a year, so my guess is in capital letters, POWER. He will make far more than he spent BEHIND THE SCENES than his salary will ever pay. It would seem that American voters would pick up on that but, they do not.
Look for instance at many Congressmen, and Senators. They come into office with a modest amount of money, and some with almost none. Six to eight years later they are millionaires on less than $175,000.00 a year. Hmmmmmm. Makes one think about those lobbyists doesn't it?
