Well The Halfrican was so lazy in office that he "saved himself" for the good times ahead.
He might have been a lazy jerk that just dialed it all in but I must admit, he was a smart lazy jerk....If that's what you want out of a POTUS you should be well sated..
He increased his net worth almost 20 fold from the time he entered the Senate till he exited the WH (20 million) and since leaving office his net worth is somewhere around 135 million, possibly much more depending on how his investments do.
